You go through a screening interview with hr, then a behavioral interview with some devs aswell. If you are in line with what their culture is like and you answered the behavioural questions right, they will call you in for a technical interview. For the technical interview make sure your code is clean and refactored.

Waste of time. After a 15 min interview where HR did not ask me a single question regarding my coding capabilities, work experience, or projects they made me wait 2 weeks to simply tell me "we have moved on". Somehow with 3 non technical questions they concluded I was not fit for the job. By far the least effective interview I've had. Don't waste your time.
