Marvell Technology interview questions

I had completed all three rounds of interviews. Got an email saying I have completed all the rounds and asked for my documents. Never heard from them later. The recruiters and HRs who contacted me for the role had their phone on auto reject so there was no way to reach out to them. Not even a generic mail saying we're going ahead with another candidate more suitable blah blah. So it was not a good experience.

I have interviewed for 2 positions for this company and they take long to get back to candidates because they use a bunch of vendors for contracting positions. That shows how slow they are to make an informed decision. My job experience matched 100% to the position they interviewed me for and they show keen interest in your profile in fact even tell you they were impressed with you a lot. And then suddenly without any feedback they will choose another candidate. Their people operations team is a mix of highly experienced people and some that have joined the company in past couple years. I am sure they are afraid of hiring better caliber candidates so they reject them due to job insecurity.
