Code Debugging: 7 questions C/C++/Java (20 minutes)
Coding: 2 questions (70 minutes)
Workstyle Assessment: (20 minutes)
Reasoning Ability: 24 questions (35 minutes)
Technical Round 1(90 minutes): First, the interviewer asked me to introduce myself. Then he directly jumps to coding questions.
Initially, I told him the brute force approach using insertion sort, explained to him its complexity. Then he told me to optimise it, I gave him solution using min_heap and max_heap. He seems to satisfy, and he told me to code it.
2) He gave me a tree and ask me to print its different views. He said u have a fixed time(30 minutes), have to code this approach.
- Left -view
- Reverse-Top View
3) Implementation Details of
- LRU cache
- LFU cache
- Mixture of LRU cache and LFU cache
Then he jumps to the operating system and asked me about paging, cache, and what’s the advantage of caching.
Technical Round 2(50 minutes): After a formal introduction, the interviewer directly jump to coding questions.:-
Give me a situation of a company, where a hierarchy of manager. A manager can have a different number of employees who are working under him. Now, this employee can have a different number of workers who are working under that employee. This can be up to any level.
He told me to find the youngest common manager of two workers.
Solution: Basically it’s a problem of finding a common ancestor in the n-array Tree. Firstly I created an n array tree then gave him 2 approaches
- Using recursion
- First, find the path from the root to that worker and then compare the path and check the node just before the first mismatching node.
3) Maximum Profit using at-most k-transaction
I gave him 2 solutions first one was using recursion and top-down approach and the 2nd one was using the bottom approach.
Finally, the result declared after 10 days and two students were selected for the internship. I was one of them.
Thank you Geeksforgeeks for helping me prepare for my interview.
