1st interview with recruiter, second one was with hiring managers asking questions about your background and motivation, last one was a technical panel presentation with the hiring managers and about 5 people from the team

3-round interview. First was phone screening, Second was hiring manager, and third was demo presentation. The entire process took about a month. Overall, was an organized process, and no complaints. The third round was the most pressing - understanding the case, technical requirements, and product specifications can take some time. You are provided a sandbox environment and there is loads of documentation for any questions that you may have. Additionally, the hiring manager set up an informal meeting before the demo to answer any questions.
