Quant Researcher

First, they ask you to submit a ML-based solution to the hangman game. If you get ~55-60% winrate on it, you get to the next stage.
Secondly, the HR interview. It is 80% behavioral stuff and a coding problem at the end (leetcode medium). After this, your internal application is forwarded to teams, which gets a response by anywhere a vacancy is available.
Thirdly, you have to interview with the team lead of the team you get selected in. The interview is very broad (hangman solution, finance knowledge, coding, ML/DL basics, anything relevant to your resume can be asked). I could not make it past this stage.
Fourthly, interview with the CEO, Tyger. he asks you basic knowledge and gets to know you personally, if you made it past all the previous stages, you'll do good on this one. The questions are supposed to be basic and also not much of implementation involved.
