Recruiter call - 30 min First interview - 1.5 hrs Second and third - 2 hrs Usual initial screen. First round consisted of writing code in vim. Went very smooth, talked about experiences and then got to ask one of the devs about their experience currently at Arista. Second/Third round went terrible. It was a 2 hour back to back technical round at the end of the day. Interviewer was late, scrambled to setup environment while clearly not interested asked me surface level questions. We rushed through the problem while he kept asking me questions upon questions on stuff irrelevant to the problem, and about my experiences. Any question I asked about what he wanted for the api/things to account for was met with condescending remarks and another question. Third round was right after second also started late. Somehow I made it to the final round. The interview was disinterested and was keen on asking tricks of "find the bug" with C strings. He got frustrated as I was trying to find a bug, solved it for me and then called it quits. once it was end of the day. Two minutes later, I was told a "I wont be getting the offer" by who I the found out was the hiring manager, whom showed up late, and they dropped off the call quickly before I could ask if there was anything I could improve upon. Mentioned this to the recruiter and was promptly ghosted. Really poor interview experience to be frank, especially since they reached out and shotgunned through the process. Churn and burn I guess.
