I applied for Job at QSSI through online, then QSSI shortlisted my Resume among so many Resumes,After that I had a screening call, then I had Phone imterview followed by skype.

Multiple rounds of interview. Offshore round is the most critical round . The interview went on for abt 45 minutes. They usually hire for specific technology like F5, Palo Alto, zscaler etc. You should be very good in that product
