After a short conversation with the recruiter, he booked me an interview with 2 other senior engineers. While it was a pleasant conversation, it felt more like they were interested in my previous job than in me. Many questions were on how things 'were' rather than how would you do x, y ,z. It's the kind of question you'd expect for a more behavioural interview but you cannot be an assessment of your tech knowledge or ability.

A staff in TA did an initial call to screen and describe the role. Then an coding interview will be organized with 2 interviews. The code base will be sent to you few days before interview. During the interview, you will be asked to implement some additional requirements. Make sure you have TDD in mind. Then the next one is system design interview. Highly suggest to watch some youtube videos for system design interview or reading some system design books to prepare for that. The last interview will be a short chat with VP of Engineering. Overall, the experience is good and the interviews are clear and well organized. TA has done a good job to follow you through the process of interview and gives you adequate feedback from the interviewers.
