They will send you an automated invjte to an OA 2-3 days after your application, you have 5 days to complete it.
You will have 2h to complete it, 2 multiple choice questions (mine were multithreading) and 3 leetcode style questions, mine were 1 med-hard, 2 hards, all of them DP.
I did not finish the test because it kept saying my camera is not detected, but it worked on any other websites. I emailed them but got ghosted.
For an internship, the questions are very hard, imo you need to be very prepared to even have a chance.
