WANT A CAREER IN DATA SCIENCE? START HERE!
We are in an age where Data is everything. Amount of data burst every single second is humongous. Data science along with its different aspects focus on getting valuable information out of the data, for improvement of every system.
Everybody knows data science is a hot cake that sells fast and offers the most lucrative professional opportunities in technology.
Data analysis was first used to analyze data and it has evolved in modern data science.
So, what is Data Science? To simply put, Data science is the method of deriving valuable information out of large sets of data.
Data engineering focuses on building the architecture and platform for the collection of data and gives the data output in a usable form.
The three main careers with data science are Data analysts, Data engineers and Data scientists.
At first Data scientists had the role of both data scientists and data engineers, which is a huge skill set to cover. With the advent of big data, more streamlining required, thus came a new job role, data engineers or big data engineers.
The number of skilful people in data science is low, and hence there is a huge career opportunity with data science.
Let’s see the difference between data engineer, data analyst and data scientist.
Who is a data engineer?
A data engineer is a person who uses computer science engineering to build data infrastructure and pipelines for gathering and maintaining data. The main work of data engineers is to design, build, integrate and manage data and give data in a usable form for the data analysts and data scientists to compute with. They closely monitor the quality of data pipelines and infrastructure and ensure that data is accurate and easily accessible.
Some companies term data engineering as data infrastructure or data architecture & the associated job role is data architect.
Data engineers don’t involve in the analysis of data; hence they don’t involve in decision making based on data.
In short, data engineers receive, store, clean and prepare the data for data analysts and data scientists.
Education & Skill Set
A data engineer should mainly have a computer science engineering or software engineering background. They should possess strong programming skills such as Java, C#, Scala or Python. Sound knowledge in SQL and NoSQL databases (MongoDB, Cassandra DB) and frameworks like Apache Hadoop, Hive. Along with programming and database skills, data engineers should have strong mathematical(statistics) and big data skills.
According to Glassdoor, the number of job openings for data engineers is almost five times higher than that of data scientists. Even in this pandemic, there is a drop-in data scientist job vacancy, but the openings of the data engineers are on the rise.
As per PayScale, data engineers get around $63k to $131k yearly salary. The average salary of data engineers according to Glassdoor is $172k. DataCamp mentions salary of data engineers are minimum of $43K to $364k, based on years of experience and expertise.
Who is a data analyst?
Data analysts cleanse and analyze data with the help of statistical tools to derive business decisions from historical data. They focus on finding insights for specific business goals. Data analyst job will typically analyze data for a specific query and present them in visual form. Data analyst to some extent helps the organization to make data-driven decisions based on historical data.
Education & Skill Set
A data analyst can be considered an entry-level job role. They don’t have to possess strong programming skills or algorithm skills. Graduates with mathematics, statistics or any math-related fields with a bachelor’s degree can pursue data analyst jobs. The essential skills of a data analyst include statistics, communication, business knowledge and fair knowledge in excel or any computing software, tableau and SQL.
According to Robert Half Technology’s 2020 Salary guide, Data analysts earn an average of $83k per year.
Who is a data scientist?
Data scientists are actually predicting the future by manipulating data to solve critical business problems and provide predictive algorithms based on the model they used.
The job role of data scientist and data analyst may look the same on a wider level, but data scientists work with a large volume of big data and use predictive analysis, machine learning and programming skills to automate the process.
A data scientist is responsible for cleaning, processing and verifying the data from data engineers and performing analysis on the data using advanced automation and present the business with useful insights and solutions.
Education & Skill Set
Data scientists should typically possess a master’s degree in the field of Data Science. They should have extensive programming skills to create various algorithms for data automation. They should have command over mathematical and statistical skills. A data scientist should have hands-on knowledge in machine learning, coding, software development, data mining and data analysis, python, SQL and NoSQL database, python, Scala, Java, etc.
According to PayScale and Glassdoor, the average salary of data scientists ranges from $80k – $130k. As per DataCamp, a data scientist earns $34k – $341k based on their experience and expertise.
So, which one is for you? Data Analyst or Data Scientist or Data Engineer?
The job role mainly depends on your educational background and skill interest. If you are more inclined towards programming and love building things, data engineering is the way to go.
You don’t like programming but would love to compute and work with data in an analytical & statistical manner – data analyst should be your job role.
On the other hand, if you love the manipulation of data, along with programming skills and highly analytical – data scientist will be your ideal job.
In the end, it is personal interests that matter. You can develop the right skills for any of the above job roles in data science if you invest time, money and determination to learn them!
3 TIPS FOR FOLLOWING UP AFTER SUBMITTING A RESUME
It was difficult to learn whether to follow up on the days of the online resume application. You can apply the
curriculum vitae on a working board and can never contact a real person without working with a recruiter.
You will never even learn about your submission, which makes it particularly difficult to know how to track
and how to do so. But never fear, after submitting a curriculum vitae, we gathered some sound tips for
suitable monitoring solutions.Searching and interviewing will take too long these days.
This is particularly true for large organizations that still possess some obsolete, time-consuming
online application processes.Ask your client whether it was only pressing a button or if your knowledge
needs to be entered manually. When in a week or two you don’t hear from anyone in the business,
do you think that the job is a no-go job? If you don’t even know who you applied to, how can you follow up?
1. Use email at the two-week
Use email to meet the position you applied for at the two-week mark. Many companies prefer email to have
a contact record. You will find a general company or an HR mailbox for sending an email if you have
submitted through a web portal where there is no email to monitor it. Please type the name of your work in
the subject line when you send the email. Write a competent follow-up document in succinct form. If you
don’t know the hiring manager’s name, simply use the salutation, Dear Hiring Team Write that you are
following up on the specific job application and that you are extremely interested in the position.
End the email with a professional salutation and always reiterate your contact information to make it easier
for the hiring manager to follow up.
2. Try calling the company
Try to call the company. This may sound a bit like stalking today, but it’s all right to reach out over the
phone, particularly when you know the hiring manager’s name. Tend to call early or late in the day a
few times and try to reach someone before they end the post. Your name and telephone number and the role
you applied for should be concise. Thank you to the employer for considering your candidacy and for
reiterating your interest in the job. Take the same straightforward method if you have anyone on the phone.
Ask whether they need anything else to help them understand your qualifications. It’s also all right to ask
how long it takes for the applicants to study the process and take the next steps.
Thank you for reviewing your application in both cases. In both cases. Let the employer know that if you
move into the role and get to the city. Ask if you want to meet you for coffee or whether the staff should
talk about your day in the area. You should do all this carefully, politely worded and not too pushy.
It even helps to write a script before you even take your cell. Sometimes.
3. Partner with a recruiter
Recruiter associate. Associate. PRO IT KEYS can help you find the perfect job with you.
We keep our applicants updated and help them develop their curriculum vitae and interview skills.
If your resume is right, you should follow up after sending your resume. Let’s then go over some resume
follow-up tips to get this line successfully. Using our follow-up email sample curriculum vitae to see a
follow-up call script and luckily you have validated ways to track a work application.
4 TIPS TO GET VIDEO INTERVIEWS RIGHT
We also had an experience with video-interviews that went less than anticipated. Poor link, last-minute download of the appropriate software, time zone mix-ups, poor sound trust us, the list goes on! Here are five tips and tricks for more people having to work from home than ever before to interview candidates from home via video.
1. Prepare candidate
The nearest alternative to an in-person interview would be a video interview if it goes well. However, loads of things can go wrong with a little preparation on both sides, which is fairly easily controlled. Set aside some time to train your nominee, who may not be as comfortable as you are with the process.
Let them know that it is a video interview and they should use their camera. Mutual webcams are important because they mean that you can see non-verbal indications, not talk about each other, and have a much better experience in general.
Tell them what app you are going to use, so they can update it beforehand. Skype or Zoom is a great device for this because it is freemium-based available.
Provide them with instructions and standards concerning setting up a good camera. Effective lighting, clear backdrop, and angles are also of great importance.
Double-check time and date, particularly when you’re talking to someone in another time zone.
2. Try a test call
You’ll get the software downloaded in advance as the nominee, and know how to use it. Call a buddy for a check to make sure your camera and microphone are functioning properly, and you’re having fun sharing links, etc. And practice what you’re teaching to ensure your camera’s eye line, lighting, and the backdrop is all right!
3. A good microphone is important
It ‘s important to have a working microphone but be aware of the sound environment you ‘re in when taking the call. What other sounds might it catch up with? Calling from a coffee shop may look chic and trendy, but it will add to the call a lot of needless noise. Likewise, additional noise distortion produces a negative image with leaky headphones and defective devices, which wasted time. When you call from home, know who else is there and let them know that you’re getting a call and you need some quietness.
4. Still calls for first impressions
A video interview is often superior to a phone call. This will be as similar as possible to an in-person and it can have an effect on how you behave, talk, and look. Note that although you might be at home, you are also suitably representing yourself and your business with an external customer. And dare we suggest the whole way we dress properly. Too often a qualified top half and bottom half pajama-ed make appearances on video calls.
Look at the video camera so the interviewer can have eye contact with you and ask questions for better discussion back and forth. Make sure both you and the context look professional when the webcam is switched on. More importantly, before your interview, practice using your camera and the Skype, Zoom, or Interview app.
5 INTERVIEW PHRASES THAT WILL ELIMINATE YOU ON THE SPOT
Nobody wants to sound overly rehearsed during an interview. At least, you are trying to represent who you are authentically as best as you can when being judged on call, and getting each of your last lines written in advance is likely to leave things feeling stilted.
But while it might be prudent not to chart all of the stuff you ‘re going to say during the interview, experts say there are certain lines you should go ahead and intend not to tell. Beginning with 5 phrases below.
1. Negative about a previous employer or boss
I make it a point never to say something derogatory about a former employer or manager, Even though the applicant thinks the information is real, it doesn’t reflect well on the applicant or the person or business they ‘re talking about, and it doesn’t give a major impression of the candidate to the individual conducting the interview. In my mind, it is a lose-lose-lose!
2. Red flag during an interview is a candidate
One thing that often appears to me as a red flag during an interview is an applicant who is unable to provide any examples of what they have learned from a difficult work project or a demanding supervisor. If I ask a job candidate what she or he has learned from experience, I want to hear a clear narrative about the experience that explains what they have learned. Learning from mistakes indicates a desire for growth and development. An inability to learn from challenging circumstances can signal a lack of interest, or worse, it can show the applicant a degree of arrogance.
3. I need this job
Hiring managers want to see candidates interested in working for their business, but with the enthusiasm, it’s easy to go overboard, if you seem too eager or worse, desperate to get the job they ‘re going to start wondering why. Applicants of the highest quality appear to have other choices available that allow them to come off as interested but still professional. Desperate candidates tend to be passed over or offered the position with reduced compensation.
4. I don’t know
To me, the one thing I don’t know is to avoid saying in an interview. Of course, no matter how much we plan, occasionally there will be questions we don’t have the answer to immediately, but there’s always a better way to answer it than with ‘I don’t know, you can never do something to answer a question you don’t know the answer to, but consider using your communication skills to turn the question around. Take the time to think about it, maybe answer the question as if you’re talking about it, and come up with something that turns the discussion back to what you know.
5. How long before I can be taken for a promotion
This question reveals a brief interest in the position at hand today. Let’s face it, many of us have taken up a job that we see as a stepping stone toward the role that we really want, or as an entrance into our dream business. But, when you’re on the recruiting side, this issue is a red flag that the candidate focuses more on their career development than on doing the job at hand.
Finally, don’t pepper the interviewer with questions on a laundry list. If she seems interested in the discussion and encourages you to keep talking, fine, but if you see her listening, time to wrap it up! It’s best to choose a few of the most critical questions and leave on a positive note.
6 SIGNS YOUR INTERVIEW WENT WELL
You landed an interview, dressed up to impress and had a nice chat so you thought you might potentially get a work offer. Yet is there any way of really knowing if the interview was going well? Often in an interview job seekers are so focused on what they did wrong that they don’t care about the other things they did well. Although no signs are 100% foolproof, there are certainly some indications you’ve won over your interviewer.
These are the signs the interview has been rocking:
1. Second interview
The receipt of a second interview invitation is a sure-fire predictor of progress. If not interested in the recruiting manager, she ‘d be evasive about when and whether you’d like to hear back.
2. Asked for references
Bad hires have cost employers an average of nearly $17,000. When the hiring manager asks for a list of references, this means they take you seriously and want to make sure that you are a good candidate. When they are not interested in recruiting you, an organization won’t extend the time and resources to complete the process.
3. Being introduced to people
It’s a great sign to be exposed to people who weren’t on your interview schedule particularly when they’re higher up in the business. Reward points whether they are a senior executive or president. Drop-ins like that show the word about you and your skills are already getting around the office and interested in your future colleagues.
4. You spoke about the details of quitting your current job
When a hiring manager questions about how much time a transfer takes or what non-competitive arrangements may be in place, you should be confident that you are on their short list. This suggests that the recruiting manager is interested in going forward with an offer and wants to get ahead of any possible roadblocks that might slow down your exit from your current organization.
5. Salary discussion
It depends more on the stage of the interview process that you are in, but sometimes asking about wage goals is a positive sign. This means the company is considering investing in you. So come on set.
Usually, the pay problem is answered in two ways: What are your salary expectations? So what is your current remuneration? Write down your present salary to prevent misspelling. Study also the average salary of the industry for the role you are looking for. You don’t want to sell yourself short, or count yourself out by asking for too much if you are asked to offer a salary range.
6. The interview ran long
Out between their other duties, recruiting managers schedule interviews. Find it a good sign if they don’t hurry you out of the door to get to their next candidate or meeting.
Again, none of those are sure-fire signs you got the job. However, if you’ve done all right, there’s always the possibility that someone else has done that too. But if you see a few of the above signals continuously you will know you have at least one shot.
