The interview process was two step in my case. There was a phone interview followed by an in-person interview in the Waterford site. I was notified two days in advance for the 1:1 interview.

1st stage is interview with HR which lasts about 30 min. If you advance to the next stage, you speak with the hiring manager for 30 min. If they advance you, you present to a panel and the team and you'll be interviewed one on one with the team members so it can take up to 2 or 4 hours 3rd stage - Interview with panel and presentation (2-4 h)
