I applied online. The process took 6 weeks. I interviewed at Datadog in Feb 2022
Interview
As explained in previous posts, the interview process has 5 interviews and two take home tests.
- First step is a screening interview with the tech recruiter.
- The second interview is technical with some basic stats questions, LC easy/medium coding problem, and 10/15 minutes to present a technical project you did.
- Two take-home tests, one on data analysis and the other on coding.
- 3rd interview is more focused on data science. Just like the first technical, you start off by explaining a tech project you did. Then, you can expect general DS questions + some open-ended questions related to the take-home project (time series).
- 4th interview is a live coding problem.
- 5th interview is with the hiring manager. Don't be surprised if the discussion becomes technical at some point.
The interview process was very well organized and took about 6 weeks. The recruiter was highly available and gave me useful feedback after each interview.
Some tips:
- When presenting your project, don't hesitate to bring technical depth as it enables the interviewer to better gauge your level.
- Some questions are open-ended, so you are expected to show your reasoning around edge cases, potential problems etc.
- For the live coding problems, asking the right questions and communicating effectively with the interviewer is important. Present how you plan on solving the problem before diving into the code.
- For the take-home projects, I recommend asking the recruiter about the main points that will be evaluated. Unsurprisingly, you're expected to write clean and documented code.
- Prepare some questions for all the interviewers beforehand.
The process includes a phone screening with recruiter, then there is a call with hiring mananger, next it will be a tech screening testing stats and SQL, then it will be a take home assignment and final presentation.
L'entretien d'embauche est une rencontre entre un candidat et un recruteur visant à évaluer les compétences, l'expérience et la motivation du candidat pour un poste spécifique au sein d’une entreprise.
Talked with an HR manager and Senior interviewer.
Very smooth and very professional.
I have a positive feedback even though I did not pass to the next stage. Prepare as much as possible using medium Leetcode style problems
