50 min interview-easy data structures and algorithms, Linux questions, core subjects such as oops , database management systems , operating systems questions were easy to average and he wanted to ask compiler design

It was a decent interview not much hard questions were asked you just need to know the basics of OS, Database, Programming. Basic questions regarding networking TCP/UDP , how google.com works, etc.
