Answer 2

You can apply on their websites or get in contact with a recruiter. You need a cv to do that. Then you could get an interview. The questions on the interviews are algoritmic like the ones on leetcode or codewars. You will have around 5 interviews. If you do well you will get hired.

I recomand the book Cracking the code to prepare for the interview. Great succes
