I'm in college and I am searching for software engineering internships for the summer. I received a phone call and written offer from a big, local company about three weeks ago. The position starts in May.
I accepted the offer in two days (well within their 2 week deadline), and I received a confirmation email for my acceptance. I emailed them and left a voicemail saying that I accepted, was excited to join, and I had a few general questions about the process after accepting (timeline, staff account, etc), especially since the start date for the internship was so far away. I didn't get any response, and I sent a follow up email this past Monday. Still no response.
Is it normal for HR to not respond after an acceptance, and should I also stop sending emails? How much communication should I expect between now and May? Also, is there a possibility they are going back on the offer by just ignoring me? I don't want it to get to May, just for them to say something's wrong because they weren't responding.
Edited to clarify: I think my question is unique because there is such a large gap between now and the start date, and I know my current status (because the offer has already been extended to me). I am just uncertain of the expected behavior of HR for start dates that are far away.
