I applied through an employee referral in September.

A few days later, they informed the person who referred me that they intended to interview me.

I heard nothing from them for a couple of weeks.

The person who referred me followed up, and they stated they would reach out soon.

I heard nothing for another few weeks.

Finally, near the end of October, I received an email from HR (not a specific recruiter) asking to schedule a phone interview for either the week of 11/5 or 11/12.

I selected a date in the second week.

Then, the following week (the last week of October), I received another email from the generic HR address, informing me that all spots for the internship program had been filled and that they were canceling my interview.
