Discover interview questions

I went through five rounds of interviews. First was an online assessment, then an online technical assessment, and then only after completing those two online assessments did a recruiter reach out to me. After that was an interview with the recruiter, then a video technical interview, and then the final round. I went through all those interviews and was even told during the final interview that I would be a good fit. Then I got rejected after days with an automated email. Got ghosted by the recruiter too when I thanked them for the opportunity and asked for some sort of feedback if possible. Pretty sure someone else posted here about having the same experience for the same position. It's whatever, but it was frustrating to do all that just to be treated like I only sent an application and didn't go through with such a lengthy process.

I have applied through LinkedIn on Feb 13 and i have been done with screening round with recruiter ,it was good. Later he scheduled in the screening round the first round of interview it was total technical, and eventually it was 1+4 rounds, the 4 rounds where behavioural mixed architecture and whiteboard related questions. 1st round Microservices, SpringBoot, coding related syntax, basic java questions. (1hr) 2nd round was he gave me scenario i need to design architecture and some basic java questions in last 5 minutes (1hr) 3rd round Microservices based and behavioural based (1 hr) 4th round Whiteboard, he gave me an scenario ask to design architecture and later asked few questions related to that and write an basic overview code (1hr) 5th round behavioural questions (45 min) 4and 5th round was on same day with 1 hr of gap Still no idea why it was rejected. I have done well.
