Interview
It was a 1 hours interview process which involved the teams who have shortlisted you via resume, will ask you certain question based on their team's work and fundamentals so cant really tell what can they ask
1st interview - your interests, reason for application, general background stuff
2nd interview - assessment of coding skills, AI concepts, LLMs, etc., using problem scenarios (goal is to understand problem solving skills)
Seems to depend on each team and members on the team
