Tesla Software Developer interview questions

Horrible interview process. I was contacted by a recruiter and a phone interview was set up the following day. I spoke to a Staff Engineer at Tesla who told me he enjoyed our conversation and would send out a coding test for me within the next few days. I never heard back so I checked in with the recruiter for updates but didn't receive any. I didn't hear back for another week so I checked in again and my recruiter responded with a rejection email.

Very pathetic experience I had. I was reached out for the position by the recruiter only. Then he scheduled for 30 mins of call for discussing about the position. After one week one round of technical interview was scheduled. I cleared that and also cleared the online Java test. The next round was on-site interview. The recruiter introduced a new recruiter and told me that new recruiter will manage going forward for on-site interview. Two weeks passed and then I came to know that position is no longer exist and someone from internal team will fill up that. Unnecessarily wasted my time.
