Very weird process.
Had a call with the recruiter who then invited me to a call with a manager.
Manager asks me about my previous projects. Keeps saying "impressive" throughout the call.
I get a rejection just after that saying I need more experience in "DB architecture". Strange when no one actually asked me about it.
I have done DB sharding and partitioning on live production systems, only if someone asks me, I can tell them all about it.
I felt like I was just trolled. May be the recruiter wanted to fill their calendar with calls with no purpose. IDK.
