I've been contacted by a recruiter over the summer, while i was still studying, and since I was not replying she kept contacting me. I answered at some point, and I got to plan for a phone interview to discuss a fex opportunies. I've had an other interview with another recruiter a few weeks later. And while we were planning for the last one, the recruiter stopped replying to my emails and never recontacted me again. So, overall, very long process, a few phone interview, but the recruiter stopped replying at some point and left me there.
