had one phone interview where he asked me basic questions about file systems, networking and proficiency in scripting and later on i got an email for an onsite interview It was with 7 members of different team. They asked me questions about OS , multicore threaded environment, Perl scripting questions (regex) , asked me to describe what my job role would be, current job role, why i wanted to do this job, why i wanted to leave my current company, file systems basic storage/deletion memory based questions. It was a average interview and I could answer almost all the questions but strange enough I didnt receive an offer
