I have Mtech from Tier-1 university, been working in good MNC for last 3 years.
I have experience in a niche techology in system software.

I want to switch , But after reading interview experineces , I feel I am unemployeable after working on such niche technology, I havent done LLD/HLD in current profile as expected from a 3years experienced.

How do I plan to switch in top MNCs/startups ?.

Having worked on system software (C, C++) for 3 years , Is it possible to get calls from companies working on distributed systems or microservice Architecture?
