1 LC Easy level question(on Arrays)
1 LC Hard level question(on DP)
Asked to explain Builder pattern and Factory Pattern with examples
Theoritical question on inner working of HashMap
Asked one very easy sorting based question, I answered verbally so interviewer told assume I cannot use inbuilt sort method
So I told I would write MergeSort, then discussions between quicksort and mergesort and then merge sort pseudo-code

Interviewer gave option to discuss any of my project where I designed a system or go for an arbitrary system design.
Having worked for a start-up, I had an interesting project I worked on so chose to discuss my own project design since I knew it inside out, 
discussed over it 40 mins, why we chose what we chose and what other options we had explored etc.
Interviwer was happy as I was able to answer all the cross questions.

We had 20 mins left, he gave me a couple of DSA questions. 
Both were LC medium level, I solved 1st one(Jump Game 2 on LC) with DP,
but he said it can be more optimized, so I started solving by Greedy approach, 
I was able to solve it by the end but we could not go to the next question,
but I just told him that will also be solved by greedy and he said yes-correct.

Discussion on all my work-ex (at couple of companies) in depth both from product and tech perspective.
Those discussions took most of the time, interviewer gave an easy DSA question,
which was easy but it had like a paragraph that you had to read and understand what exactly is the question,
once I was able to figure it out and started writing code,
the interviewer told me its not necessary and asked me if I have any questions for him before closing the Interview
