Got approached by a recruiter so I gave it a shot. 1st round was a short take-home assignment. Mainly lets you explain a basic NLP concept and some string processing tasks. Then after I got the result from round 1, they asked for my documents to check if I'm eligible for a working Visa since I have to move abroad to work. 2nd round was an interview with their lead, they mostly asked general interview questions like What did you do before, where did you study, why this country, etc. 3rd round was 2 consecutive interviews with the clients. The 3.1 was a coding interview with 2 questions, I only did the 1st done and ran out of time. The 3.2 round was a knowledge check, they explained problems and asked what you would do with them. Then 2-3 weeks later, I got the offer.
