In first round, the interviewer has asked some questions on python concepts and gave two coding questions on arrays and Linkedlist, then, he moved to OS and asked me tell what all I knew about OS and computer architecture.
After one week I got rejection mail saying that "This role should also require strong knowledge on OS, Computer Architecture, C and C++, along with python.
He didn't ask me anything about c and c++. Even, he didn't ask me anything particular concept by naming it(he asked to tell what all I knew about OS).
