Summary
I interviewed for a Backend developer role at Apna Mart, where I faced DSA and System Design challenges across two rounds. Despite acing certain questions, I was ultimately ghosted after the interviews.
Full Experience
My YOE -> 2.8
Round 1 ->
DSA -> house robber - 2
Max water trap
System design -> distributed locking, and more high level design questions
what is race considtion
three way to avoid it
CAP theoram
replication lag
Round 2->
DSA -> https://leetcode.com/problems/longest-valid-parentheses/
give me the most optimize
what is java string pool
is there concern both string point to the same object
you have rod of 7 unit cut atmost 2 times. . give it to employyee every day by one
Aced all question about rod cutting
verdict -> Ghosted
