I was called by HR and scheduled an 1:1 interview. I was asked to write a test on C and Linux. Also there were questions related to backtrace messages generated due to oops or some output generated as a result of running some command/stress tests on ARM, MIPS architectures etc.
Later, i had an interview with PL, and PM. And i was again called for another round after 2 weeks, and manager and HR happend on the same day. After this, i was offer within 3 days. And i accepted the offer.
