First interview was with the recruiter to review candidate's qualifications, work history and expectations for the future role. This was done over the phone and the recruiter was in another country. Recruiter called at the time arranged and there was not a delay.
Interview + Presentation to the hiring manager and panel of R&D and Design.
Interview with hiring manager testing for the right experience followed by a home assignment improving their product and presenting it to the panel.
3 rounds done and after that Recruiter told 1 more round is there. Next, recruiter stopped responding to my calls. At least have courtesy to respond to mail/ call the candidate when the candidate has given enough time
