DISH Network Technologies Software Engineer interview questions

The interviewer had asked questions on puzzles and 1 coding question(Finding the first character in a String which appeared only once). They had even asked about projects on my resume and questions on BFS,DFS and few core topics.

3 rounds - online coding, aptitude round, technical interview round and then a HR round 1. Online Round :- I do not remember the exact details, but what I can say is that this company came through college placements. 2. Technical Round: They asked about concepts in OOPS , asked me to solve a few question on linked lists, and arrays. No Tree or Graph questions. Asked me about my projects and what technical subjects interests me. 3. HR Round- asked how I will handle stressful tasks on some days, how do I plan to be organized.
