I applied to a summer internship position online some 3 months ago. A few days after submission, my application moved to the "review" stage and since then, I have heard nothing from the recruiter. Though many online advertisement are indeed application black holes, I reckon this one is legit as I personally know people with very similar profiles to mine who successfully applied last year.
Therefore, I decided to contact the recruiter by email some two weeks ago. In the first two weeks, I sent two mails per week, one early and one late in the week. This may sound slightly excessive; however, when I first wrote to this address 3 months ago to make an edit to my application, I got an answer within minutes, so I don't think I should be blamed for that. Having obtained no response, I tried to contact the person whom I thought was in charge by LinkedIn. I say "thought" because the mail address is a generic one (not personal), but he was the guy who answered to me 3 months ago. Anyway, he ended up ignoring my message. This prompted me to adopt a more "aggressive" approach this week, with daily mail reminders. But to no avail...
What do you believe I should do in these circumstances? Should I also send a reminder to the guy on LinkedIn? Switch to two mail reminders per day? Try to reach them by phone?
