I applied through a recruiter. The process took 3 weeks.
A recruiter reached out. There was a phone screening and then another HackerRank LeetCode-style interview. The process was nice and there was feedback along the way. I didn't pass the LeetCode interview although I answered it correctly.
Easy-medium LeetCode - two pointers, sliding window with a twist that's related to Datadog world: bucketing of metrics, aggregation of logs.
The following metrics were computed from 115 interview experiences for the Datadog Senior Software Engineer role.
Datadog's interview process for their Senior Software Engineer roles is fairly selective, failing a large portion of engineers who go through it.
Candidates reported having very good feelings for Datadog's Senior Software Engineer interview process.
