Align Technology R&D Engineer interview questions

Two stage Interview Process: 1. First technical interview about experience and skills: was confronted with an actual business problem they are facing and was asked about how I would go about solving 2. Coding and Machine Learning Interview: was held as two separate sessions - the coding one was a classical Leet Code interview with additional technical questions on ML concepts in the final part of the interview - for the ML Interview I was asked to select and review a paper (I chose "Attention Is All You Need") from a list they gave me which we then discussed in quite a lot of detail
