The OA was not your typical LeetCode-style OA :) it's a nice design interview to test your ability to write good code. As for the interview, I had 3 rounds (around 1 hour each), and I was asked about things from my resume, OS and Networks in depth as well as C++ STL in depth in all three of them. There were a couple of DSA questions asked as well.

Question 1
Implement queue with stacks in O(1) push/pop complexity.
I interviewed at APT Research (Dhanbad-Cum-Kenduadih-Cum-Jagata)
Interview
DSA questions and grilled me on C++ Fundamentals along with question on Computer Networks. Adding words to complete the word requirement hence the rambling appended at the end, Pardon the rambling but 30 words are a lot.

Question 1
Gave me coding problem solution i submitted in OT and asked me to improve it's quality
I applied through university. I interviewed at APT Research in Aug 2022
Interview
The company visited my campus for internship process. I had cleared the written test (coding round) . I remember it had 5 questions all on the graphs . Then in the interview, I had the first spot . Interview went great , there were 2 concecutive interview rounds with 2 panelist in each of them . First one was cpp round , asked easy to medium level cpp question.
