Align Technology Frontend Engineer interview questions

Interview consisted mostly of theoretical questions, without live coding. Two interviewers (actually teamleads of product), very informal, we've gone straight to mean tech talk, they were very polite and interested. Later there were little additional section with PM, but it was rather formal. After i've received a job offer, they kindly accepted my request to have a talk with team members during one of workdays , so i could get first-hands experience before acceptance.
