DSA and debugging round

I was asked 2 dsa questions and 1 python debugging question Both are standard dsa from striver sheet

first was I have to find longest subarray with k distinct elements so we can do using sliding window and then second dsa question was Buy and sell stocks 2 on leetcode

then in debugging I was given a python code which has some error and I have to debug that error...it was simple question...it just has syntax error in declaration of 2d array and some indentation errors

Those who solved all three were eligible for round 2

In round 2 , they grind me upon my resume and intern project. They asked me questions related to high level design, devops , agentic AI, langchain , redis and all such topics because I have mentioned them in my resume

it was totally resume questioning round at the end, to check my implementation they give me LLD code, like to implement a data structure which will be FIFO and If we want to remove a particular no. even from middle then I have to do it in TC less than O(n2)...I implemented binary search tree then he was satisfied and in same day evening I got mail of getting selected
