Datadog Software Engineer- Early Career interview questions

The process is long but well explained and the recruiter was very kind. Included a lot of technical tests. The recruiter tries to know well the candidate to search for the best fit on the company.

Recruiter talk followed by technical interview with an engineer where I had to talk about a past project and did 2 exercises (2 algorithms and get the time and space complexity for both of them) as an assessment. Unfornately I did not past the technical interview. Now I am waiting to receive a feedback.
