The Three Kinds Of Data Science Project Exams That Show Up In A Data Science Interview

All that you've been told is that, at some point of your choosing in the next few weeks, you'll be given 4 hours to ingest and operate on a sizable data set using your programming language of choice.

You wouldn't worry about the data science project exam if you were already expecting and were excited to do it because it would be a great chance to show off your awesome skills.

By having the system in place, knowing the industry, and knowing the potential questions they'll ask - you'll know exactly what to study and practice.

Know the three kinds of data science project exams given Figure out which kind of exam is most likely to be given Come up with a system for approaching each kind Practice, practice, practice by creating data science portfolio using techniques in these two articles: How You Should Create A Data Science Portfolio That Will Get You Hired and How To Choose A Data Science Project For Your Data Science Portfolio.

This will be heavy on modeling and statistics and you'll be expected to complete an end-to-end walk-through of how to prepare, plan, perform, test, and deliver the model based on the data.

Since it is a combination of both kinds, you'll be expected to provide more work which shows your thought process and critical thinking behind the decisions that you make.

After all, this is part of being a data scientist - you ask the customer / your boss / your teammate / your colleague for more information to make sure you understand what they want.

The companies that don't give you more information do it because they think that it gives a clearer picture of what your actual abilities are rather than what you were able to study for and possibly memorize.

If they turn down your request for more information, then here is another way to figure out what type of project you'll be asked in the exam - look at the job ad.

Does the ad say that you'll be working with business analysts producing reports and looking understanding the data - then the interview project exam will most likely be exploratory based.

Does the ad say that you'll be working with the infrastructure team to optimize some models already running - then the interview project exam will most likely be modeling based.

If the ad says that you'll be doing a mix of things and working with many teams from marketing to infrastructure, then most likely the interview project exam will be a combined approach.

If you find one or a few, read through them a few times to figure out if they are the type of job to give you an exploratory project exam, a modeling project exam, or a combination exam.

Metis is a data science educator that accelerates the careers of data scientists by providing full-time immersive bootcamps, evening professional development courses, online training, and corporate programs.

This is largely driven by the exponential growth of available data (2.5 quintillion bytes of data are created daily and 90% of the world’s data was created in the past two years) and the narrow set of specific skills required to extract value from that data.

As a result, the number of data-related job postings has surged and median salaries have risen as well, leading to “data scientist” becoming the best job in America in 2016 and 2017 according to Glassdoor.

A job posting for a Data Scientist might describe a role identical to others calling for “data analyst,” though there is usually more diverse coding skills needed for a data scientist job.

They help identify opportunities for companies to use data, while also finding, collecting, and integrating relevant data sources, performing analyses of varying degrees of complexity, writing code and creating tools that teams and businesses can use over time, and telling the story of what they’ve done to company stakeholders.

On each of the five projects, we teach students how to identify the problem, extract and clean data, analyze and interpret data, and communicate the results, both visually and orally in a presentation.

You’ll have one-on-one meetings with your career advisor, exposure to industry experts via our in-class speaker series, workshops focused on resume writing, LinkedIn, and salary negotiations, mock technical interviews with professional data scientists, and more.

However, we do guarantee to: While our hiring network is largest within our home bootcamp cities of Chicago, New York City, Seattle, and San Francisco (and therefore many local companies attend our Career Day events), we're also dedicated to helping those who wish to connect with companies based outside of these areas.

Women, members of underrepresented demographic groups*, members of the LGBTQ community, and/or veterans or members of the U.S. military are eligible to receive a $3,000 scholarship toward their Metis Data Science Bootcamp tuition.

Try scoring yourself using this brief self-assessment: Statistics total = _____ Programming total = _____ Personality total = _____ If you scored a six or greater in each of the above categories, you may be the kind of person we’re looking for.

Of course, the bootcamp itself will be much more challenging, involved, and technical, but this assessment highlights the combination of skills, interests, and personality we think are necessary for a seriously considered application.

Our bootcamp focuses on applications, so the computer science material covered within the bootcamp will be narrowly focused on topics in data structures, algorithms, input/output, and Python language that are pertinent to the data science workflow.

Students build a strong foundation in the Python language, the unix/linux command line, machine learning packages such as scikit.learn, other statistics modules including scipy and pandas, web scraping packages like BeautifulSoup and Selenium WebDriver, PostgreSQL and mongodb databases, collaborative coding under version control with git, working on remote cloud servers such as rackspace, custom visualization tools, especially matplotlib and D3.js with support in HTML, CSS, JavaScript, and web hosting.

Each student should expect to spend approximately 60 hours on tutorials as they become familiar with Python, take a Command Line Crash course, go through a number of package installation tutorials (i.e., Numpy, Scipy, pandas, Scikit.learn), and do some preliminary linear algebra and statistics work.

The pre-work is intended to provide students with the essential background and foundational knowledge they’ll need in order to start the bootcamp and hit the ground running.

You soon make your own choices when tackling data science problems, and with each project, you get concrete, shareable results like blog posts, graphs, and/or reports, and you will conclude with a story of what the problem was, how you approached it and solved it, and what the results look like.

Unlike some other online course options out there, which might consist of pre-recorded lectures, our courses allow for interaction with the instructor, teaching assistants, and other students, and because these are on a set schedule, you’ll be held accountable to actually attend, do the work, and learn the material (which is what you’re really here for anyway!).

The Flatiron district in Manhattan is bustling – filled with many eateries, bars, comedy clubs, theaters, parks, and central to a number of subway lines that provide access to the nearly endless things to do in New York City (including tons of data and tech Meetups and events!).

Pioneer Square is a vibrant part of Seattle with lots of different places to eat, things to do, and bars to check out – additionally, we’re located within walking distance of Seattle’s professional sports venues, Quest and Safeco Fields.

Data science code testing with the UCI adult income prediction dataset

This article gives preliminary guidelines for testing code in a data science workflow.

But for data science, it's often not clear what that means and how you should test code for different stages of a data science lifecycle, such as: This article replaces the term "unit testing"

It refers to testing as the functions that help to assess if code for a certain step of a data science lifecycle is producing results "as expected."

Use the following steps to set up and run code testing and an automated build by using a build agent and VSTS: Now every time a new commit is pushed to the code repository, the build process will start automatically.
