I applied through a recruiter. I interviewed at Datadog (Tel Aviv-Yafo) in June 2026
Interview
They will let you go through 3/4/5 sessions, an hour+ each, and then eventually won't even let you know you didn't pass (even after 3 weeks, yep) if you won't reach out manually. This is how much they care about candidates. Take that into consideration when you think about starting a process. Super disappointing.
