Went through 5 rounds, dsa, dsa+lld, dsa+hld, techno-manegerial with Director/Head who was mostly interested in flows, basically how you debug/deploy/work. Final was an HR round which was more of a standard discussion. DSA - easy to medium, mostly strings. LLD - Started with solid principles and day to day use. Then how would you design async processes, multithreaded systems, atomic/volatile keywords, usecases, drawbacks, etc. producer consumer problem and it's soultions. Queues, backpressure, blocking queues, etc. HLD - semaphores, scheduling system design problem. Cleared all rounds but no offer extended due to position being filled.

Phone interview, then one face 2 face technical, then offer the next day. Manager fell asleep during interview, the whole panel saw it and we just kept going. The technical questions were in line with the position I was applying for, except for recalling from memory a config.xml from Hibernate.
