Just like any other tech company interview. You meet with recruiters then your manager and some other team members to see if you are a good fit for the job and team
I applied through a recruiter. I interviewed at Roku (London, England) in Nov 2021
Interview
Pretty straightforward. Good conversation with recruiters and passed first step. Moved to technical interview in a second phase with other team members and manager and finally a last interview with manager/director.
Interview questions [1]
Question 1
Technical questions based on the job description, read that and study the main requirements and you should not have a problem if you also have the experience on them.
