ADTRAN Software Developer interview questions

No automated tasks or programming tasks at all, instead an in-person meeting with the team and programming tasks describing what your experience is and describing some side projects etc. There was only one meeting after their internal CV screening. The response was rather fast, but the initial employment was rather slow. Ultimately I joined different team than I was talking with and worked with different tech stack.

First round was based on mcqs of computer basics like os,dccn,DBMS logical questions. Followed by 2 technical interview .in 1st Tr they asked about linked list and network concepts was about 1hr 30 min. 2 tr was based on more dccn concepts and project. Next was hr round they asked about family background,tell about yourself,about ADTRAN .
