NetApp MTS-4 interview questions

The interview experience was good. There were total 6 rounds for me . 1. First round was a online assessment or coding round. The question in that was a topological sort question on graph and the time given was 30 minutes for that . it was not a video round and no body was there to monitor it. So it was ok . 2. Had to visit the Netapp office for the next 3 rounds of interview. Second round was with a Senior engineer, he asked questions on Linked list , and some other programming questions. Reverse a Linked list with recursion. Details on the projects done so far. Complexity and details about projects 3rd round was with another engineer and he focussed on the Multithreading concepts. All OS related concepts and program on multithreading. 3rd round was System Design round and he asked question on how packet flows in the network . The details of which all data structures can be used in routing table. How routes could be learned, etc. AVL insertion , deletion Other tree basic questions 4th round was a video telephonic round next week and he was very helpful guy. He focussed on the Programming ( Delete leaves having even value and even after deleting leaves if the next new leaf also is even , delete that as well.) Find kth smallest element without using any extra space . So we cannot use priority queue and other techniques in this. System design question on thread pool. 6th Round was a managerial round and she focussed on all the projects and details of those projects. I got selected in Netapp but the package offered was not as per my expectation so had to deny it .
