<p>There are a lot of reasons for multiple rounds, it isn’t necessarily a sign of dysfunction, but it can be of course. </p>
<p>In some cultures fit is important and they want consensus, in our development teams we tend to have people see a wide range of people from the different areas, because technical prowess is not the only thing, fit is important, too, we run a small team, collegial, highly hard driving culture, and someone who doesn’t fit will cause a train wreck. </p>
<p>We generally do a phone screen with a tech person or two, if the person seems good, we bring them in for live interviews, usually in a couple of rounds, to have different tech people and then finally the cto to talk to them. We don’t do everyone and his brother, but it can take several rounds. We don’t have HR interview candidates, we get the resumes and decide who to see, in part because of bad experience with HR people interviewing and rejecting people for idiotic reasons, like “I didn’t like them” (I once had an HR person nearly mess me up on a prior interview, she decided unilaterally to reject me, fortunately the head of the group got wind of it…I am in for an interview at 7:30 in the morning, I had been up all night with a prod issue, got to sleep at 4, got up at 6…I was with the person who would become my boss, he ran into her in the hall, went over to ask her what had happened, and the idiot told him “Well, why would you want to hire him? He looks like he was partying all night”…my boss said 'He was up all night solving a production issue and had maybe 2 hours of sleep…I guess we only want people who work 9-5 and get 10 hours of sleep, huh?"). </p>
<p>Some companies are dysfunctional, they think that doing that will mean getting a good quality candidate, by making them see everyone or dragging it out because 'someone better is out there", and that doesn’t work any better, and quite frankly, the psych tests, personality profiles and such, don’t work any better, there isn’t any study that has shown they increase the yield of quality employees, but they do make firms a lot of money who claim they do (there are studies that indicate they actually tend to have a negative correlation, like companies that hire only 4.0 gpas). </p>
<p>What really bothers me is the companies where you go through interview after interview, you get positive feedback, then suddenly nothing back at all…very unprofessional, but many companies seem to think that they have the upper hand and they have no obligation to be professional, a lot of the big banks are like that. They may think that, but companies that have a reputation for doing that also lose good people, who won’t put up with that crap, and the people who will put up with that often aren’t particularly good IME. </p>
<p>What is sad is people can pass through the interviews with flying colors and then the job is no longer open, either you have companies that literally don’t open the req until you actually have someone (idiotic, but that is beancounters), or they decide stock analysts won’t like you hiring.</p>
