It took about 3 weeks. I was in touch with the HR department, then I had a first talk with the Hiring Manager (usually companies would have a first talk with HR before the Hiring Manager, so I appreciate that they cut that step). Then I had a few calls with other team members (3 calls in total), and finally a last call with the Hiring manager. I did not have to do a case study, but I shared previous work examples per email. Overall the process was quite fast and well organized and everyone was flexible and very nice! All interviewers were well prepared with good questions.
