HCLTech Lead Engineer interview questions

Two rounds F2F. They gave me simple code to write. Asked me about design patters, collections, multithreading, They also asked me to write code related to binary and hex numbers. Overall this was an easy round.

Interview process took 1 day. Interview scheduled by talent acquisition through naukri portal, have two rounds! one is written test and another technical. Written test is very easy, but technical round is difficult with two managers. Interviewers asked me to design and develop in paper, giving 40 minutes of time. Good experience.
