The interview process was long and had a great many stages. I understand that's the "best" way to filter candidates, but if I had been in another interview process at the time, I would not have continued with Datadog's process.

The interviews consisted of:

• Recruiter Screen
• Coding Interview
• Take-Home Assignment
• System Design
• Coding Interview
• Hiring Manager

They provided detailed feedback between rounds, which was great.

In general, I think I did well, and the interviewers were nice and accommodating. The exception for me was the hiring manager interview, which felt like just a "going through the steps" kind of interview instead of a conversation. The interviewer also implied I was lying on my resume, which is not true, but perhaps poor English made it seem so. From that point on, I felt out of it, which inevitably meant it went terribly.

Overall, a good experience, outside of that last interview, of course.
