First-hand accounts from people who interviewed at DHL.
Data Science Intern
The interview had a pleasant atmosphere and felt like a conversation between equals, which was very nice. It started with general questions about you, followed by technical questions about programming languages you've used.
- Could you describe yourself?
- What programming languages have you worked with?
Data Scientist
Application process took around 1 month. Started with an online application, a presentation interview then a technical one. The team was professional, the questions are clear. Be careful with the two things : the timing : try not to spend much time on introductions, try to bring the interview rather to the business case asap, do not focus on providing solutions like 'we should use this algorithm or method', try to develop and logically justify your answer.
- Can you walk me through your projects and the tasks you've handled?
- What's your approach to dealing with missing values?
- What kinds of data have you worked with?
Data Scientist
I applied online for the Data Scientist role in early February. The head of business intelligence contacted me first for a 30-minute chat about my motivation and background. Next, the head of data analytics scheduled an hour-long phone interview to review my CV and background again, and then present an analytical case study related to current team projects. This case involved analyzing a market research survey on shipping preferences. I was asked about my approach to data mining, specifically data cleaning, handling null values, and dealing with inconsistent or erratic responses. Then, I was given three percentages: 78% yes for company A, 71% yes for company B, and 48% yes for both. I needed to figure out if these numbers were correct. The interviewer was looking for a Venn diagram approach to show a total over 100%, indicating an issue. While I suggested a data-driven method, the Venn diagram solution was preferred. Finally, I was asked about statistical methods for comparing two populations, like the K-S test or Chi-squared test. The interview ran over an hour, and the interviewer noted that such a business case would be better suited for an in-person discussion with pen and paper. I was asked about my availability for the next three weeks, and they promised a decision on moving forward within a week. Unfortunately, after two weeks with no response, and another two weeks after my follow-up, I received a standard rejection email from the head of business intelligence, with no feedback on the case study. I found this unprofessional, especially given the role wasn't entry-level.
- Considering 78% of respondents agreed to ship with company A, 71% with company B, and 48% with both, what is your assessment of the consistency of these figures?
- Can you describe a statistical method to identify differences between two populations?
