Infinity Stone interview questions

Got on a screening call with the recruiter and everything went well (at least I thought so). Recruiter told me I can expect further instructions for the next (technical round) in 2-3 days. Received a rejection after a day.

The entire interview process consists of 5 rounds. First is the recruiter call, followed by 2 rounds of coding(one based on Linux and the other one was on Blockchain) followed by 2 rounds with the founder.
