- Explain the platform project and your contribution towards it
- Hackerrank: Find if the string is valid or not - paranthesis validator. Follow-up question to understand if the input is super high, and the memory overflow happens that heap is full. How will you solve the problem?
R2
Coding round in hackerrank, he asked me to design a document creator system, maintain versions, retrive all the versions, update only on the latest versions, etc. It was focussed on OOP, and few questions about my decisions like ArrayList vs Hashmap vs linkedhashmap, how to return objects that can be immutable, how to avoid race conditions, etcInterview Questions (6)
