Slack Sr. Software Engineer interview questions

Long interview process. Recruiter screen, manager screen, code review take home (I spent 1.5 hours). Then a final loop with system design, coding (1.5 hours), and 2 behaviorals. The managers I talked to were great, but none of the engineers seemed engaged at all or like they wanted to be there. After the final loop (which I thought went well) I was ghosted by the recruiter, he didn't even respond after I followed up a couple times asking for status. It's unacceptable to not even get a generic rejection email considering all the time I put into this interview process. Complete waste of time.

The worst interview experience I ever had. The recruiter reached out to me for this position and after recruiter call, I had one Hiring manager call and I had to follow up couple of days later and was responded in a minute about next steps i.e. Take home Code Review. The take home assignment is a complete waste of your time, they allow you 24 hours and even if you followed all good code review practices, you have no idea about the interviewer is expecting. Then comes the most frustrating part, until this time the recruiter was very responsive and providing detailed answers for queries but after this round, no response even after I had followed up twice. I was ghosted without even a result. At least in normal interviews you can get a sense of whether interviewer was happy with you. Giving take home test and wasting 3-4 hours on their buggy code is useless.
