the overall interview process took more than a month and there was a recruiter call, then a hiring manager interview, followed by an assignment and presentation (final round). What I didn't appreciate was asking for 5 whole references to multiple people. My references put in a lot of effort to give me these references so thought it was pretty unprofessional to ask before an offer was made, which is what i've usually seen happen. Think it'd definitely be worthy to change that process.
