First, you go through the company's interview process, which consists of three stages.
The first is a screening with a recruiter. The second is a technical interview. There's nothing special about the second stage — it's all very reasonable. Typically, you're asked a few theoretical questions from your stack and given a few tasks to solve.
The third stage is an interview with the managers of your local unit. Here it's enough to simply show interest and come across as a reasonable person. They'll also clarify the salary you're expecting to receive.
If they give you an offer and you accept it, then — as in my case — you'll be placed on the bench and will spend some time looking for a project. For me, this took about a month. There really are a lot of projects, so there's plenty to choose from. Project interviews are also a thing. From there, it depends on what you land: sometimes it's enough to just chat with the team, while other times they run several rounds of a full interview.
