Applied online, they responded within a week and set up a time to discuss the positions available.

I got a call sharply at the mentioned time. She told me about the type of work they do at Facebook, asked me about my interests, and at the end, told me to prepare for the initial technical screening.

I scheduled it two weeks later. I got a call from the interviewer. He introduced himself, briefly told me about the work he does at Facebook, and then asked me to open the CoderPad link that I received via email.

I was asked one standard programming question. The call lasted about 40 minutes. At the end, he asked if I had any questions and concluded the interview.

I'm still waiting for their feedback (it's only been 2 days now).

Max occurrence letter in a string.

[Kept on adding constraints like: ignore spaces, special characters, case insensitive.]

Later asked about space and time complexities.
