Full Experience
Had an opportunity to interview with Datadog for Senior SDE. Don't remember all exact questions, but all of them were mentioned here, highly recommend to go through all posts where company is mentioned. What remember:
- Had Query Log match from here: https://leetcode.com/discuss/post/5154052/datadog-sde-2-new-york-rejected-by-anony-3del/
- For System design had exactly this question: https://leetcode.com/discuss/post/6055640/datadog-onsite-design-reddit-rplaces-by-e75ft/
Expectations from coding - running code, that passes tests that you write by yourself + what interviewer would suggest. You can run\debug (with logs) code as much as you want.
