Capgemini Senior Java Developer interview questions

Two technical rounds of interview and one HR discussion. In first round they ask me about all the topics like java 8, spring boot, microservices. and in second round most focus on programs, they given 2 to 3 programs to write with different approaches.

2 technical 1 HR round is conducted. The questions were quite easy. Should be strong in java streams and frequently asked questions to crack the interview. Overall experience of Capgemini hiring is not good.i was shortlisted for every interview they took but no response to release offer letter. Very bad
