HCLTech Senior Developer interview questions

I went to HCL for interview process two times but my experience there both the times was too bad. I didn't find any management for conducting the interviews & they had called the candidates in large number. Moreover, second time, I felt even the interviewers were just passing the time there & weren't serious regarding the interview process & many candidates were told to go after letting them wait for the whole day. That was really disgusting of them & after this experience, I never went to any HCL location for any interview, in-spite of getting many calls again & again.
