The interview process is commonly described by candidates as "intense". It generally begins at 9am, and consists of the candidate presenting an hour long seminar on a research topic of their choice (relavant to the position), followed by a series of interviews. The interviews will be a mix of one-on-one interviews and groups of 5-20 people in the peer group for the position under consideration. While there can be long delays between the opening of a position and the start of interviews, hiring decisions usually follow the interview of the top 5 candidates fairly quickly. Drug test and background check are required. Salaries, number of weeks of vacation, start date, moving expenses, and temporary remote work arrangements among other things are negotiable for senior R&D positions.
