The questions are designed to test coding ability, problem-solving skills, and creativity.
Such questions will require some sort of data manipulation using the code to identify insights. The most tested concepts on data science interview questionsĪs you already saw, coding questions are the single most important topic in data science. Now I want to guide you through every question category and show you some examples of the questions being asked. I find that reasonable, considering the nature of a data scientist role. Other question types, such as algorithms and statistics, are also fairly significant 24% of all questions come from these two categories. Coding-type questions are widespread, comprising more than one-third of all questions. Coding and modelling are probably the two most important skills for a data scientist.
It’s not surprising when you think about it. More than half of all questions come from that area. Translated to percentages, the chart looks like this:Īs you can see, the coding and modelling questions are most dominant. This chart shows you the question type per category according to the collected data. What types of interview questions should you expect? These categories are the result of an expert analysis of the interview experience description taken from our sources. The questions are sectioned into pre-determined categories. To be more precise, there are 903 questions collected over the past four years. I gathered data from various job search boards and websites and company review platforms such as Glassdoor, Indeed, Reddit, and Blind App. Description and Methodology of the Analysis To help you prepare for the data science job interviews, I have reviewed all the applicable questions and separated them into different question categories. This is expected, considering the role of a data scientist usually incorporates so many areas. Data science questions asked can be very broad and complex. To get such a prestigious job, you have to go through rigorous job interviews. To confirm this sexiness is still ongoing, the info from Glassdoor shows being a data scientist is the second-best job in America in 2021. Back in 2012, Harvard Business Review called 'data scientist' the sexiest job of the 21st century, and the growing trend of roles in the industry seems to be confirming that statement. Leaders who do the same will build trust which is as essential to success as any tangible item on a balance sheet.Becoming a data scientist is considered a prestigious trait. She does precisely what great leaders do she communicates in a way that is congruent with her message. Maybe a Harvard Business School professor isn't who you would look to as a role model, but don't let her academic credentials and role fool you. A warm sense of humor also makes her easy to listen to and memorable. She has the rare quality of embodying the very concepts she explains: authenticity, use of rigorous logic, empathy and absence of distraction. These ideas, and others that Frei describes in her book and TED Talk are not the only reasons she is compelling.
Distraction is more than rude, it leads to mediocrity. Leaders who think their distraction has no effect will find themselves surrounded by others who don’t pay attention, sitting in meetings that drag on needlessly, and explaining poor outcomes. Worse, leaders who ignore people signal to everyone present, “this person’s ideas don’t matter and neither do they.”įrei says that leaders need to understand, “under what circumstances and to whom do you show your distraction?” It is important to understand this behavior because the consequences have a big effect. Ignore the contributions of someone, especially in public, and they will soon believe that their efforts aren’t important. When people are ignored, they lose enthusiasm. Clark’s decision is a great example of a decision that leads to a behavior that, in turn, becomes a valuable habit.Ĥ. When asked what she chooses to be bad at, Dorie Clark, a marketing strategy expert and author of the bestseller, Stand Out, said, “email.” While client messages are a priority, requests for favors, are left until time permits.
