There were 2 coding questions to be solved and 20 MCQ questions. Both the section have individual Cut-offs. Many students after solving coding questions was not selected because they didn’t cleared MCQ’s cutoff. Level of coding question was easy.
Q2:- https://www.interviewbit.com/problems/min-jumps-array/ .MCQ’s was based on DBMS and OS.
Out of approximately 260 students registered 60 students cleared Online Round .
Interview Round 1 :- (Approx 70-80 min)
The interviewer asked me to tell about myself and then started things from my resume.
Since i have developer kind of profile and some good internship experience, he started with the projects i have done in my internship and was quite impressesd . So this discussion went for 20-25 min. Then he shifted to DSA and asked 3 questions :-
Q1 :- https://www.geeksforgeeks.org/reverse-alternate-levels-binary-tree/ This question took me 20 min to solve . I told me 2 approach with Time complexity O(n) and space complexity O(n) and O(1) .
Q2 :- https://www.geeksforgeeks.org/print-nodes-distance-k-given-node-binary-tree/
Q3 :- https://www.geeksforgeeks.org/find-a-tour-that-visits-all-stations/

Q1 :- https://www.geeksforgeeks.org/optimal-strategy-for-a-game-dp-31/

I solved both the questions. If you are preparing for Oyo, prepare well for topics like DP and Tree. Most questions are asked from these two topics . 2nd question took me approx 25 min to solve. Then interviwer shifted to DBMS, few questions was :-
Tell me about ACID Properties.

Explain different types of normalisation.
Then interviwer shited to os question. I didn’t revised my concepts in OS i told him about it, Still he asked about
What is thread
Process vs Thread
Different Types of scheduling algorithms.
Thread loop questions.
I didn’t remember i answered any of these question perfectly. Just Prepare OS and DBMS as best as you can for OYO.
There was 3rd round for few students. I was told to wait forr the result . At Last i was offered a SLI with OYO.
