Interview process, exam, and hiring was done in a whole day. The exam was pen and paper and it was mostly patterns and fundamental mathematics. The interview with HR was quick. I passed the first round of interview. Then for the second round, (they said I can go home after making us wait until 5 PM) because the department that they endorsed me to was busy today and could not conduct my interview. I never heard from them again. After this experience, I did not like the impression the company gave me, and I did not look forward to proceeding with them.
