YOE: 10
Working in a IT backend of Financial firm.

Intial Round:
Standard pattern:

1. First 5/10 minutes the interviewer wanted to go through my resume. Unlike other candidates, I was asked some what indepth questions about my current work. It lasted 10 mins I guess.
2. 2 questions:
3. LC easy quesion related to BST. I made a mistake, providing the answer to the question as Binary tree instead of Binary search tree.(I realized later) The solution is correct but complexity is wrong.
4. LC hard question related to two pointers (althought i feel it is of Medium diffculty.) He was pleased with my solution.

Couple of days later:
Got the email: "You are in final round".

D-Day: 5 rounds (3 coding+ 1 design + 1 behavioural)

1. Coding rounds went well.
2. Although, I perpared well for my behavioural. I went through my resume and recalled all the incidents. I realized later I gave a vague/convoluted answer for a question. Probably this could have costed offer.
3. System design: I believe I did reasonably well. Okay. There was some internet lag/delay from the inteviewer end, sometimes he could not hear what I was saying . I had to repeat it again. The time was not enough.

Got a standard rejection response days later.

Overall nothing unexpected, but prepare well. Make sure you practise everything.

update:

I was using https://app.diagrams.net/ for system design. I had a fallback whiteboard as well.
Just practice well in whatever you are using. Target to complete within 30 mins.

As I mentioned, questions were not unexpected. Those are more or less standard questions. Try proposing multiple solutions if possible.
Unfortuanely, I cannot share lot more about questions due to NDA.
