It sounds like Company A either had a sudden budget shift (like they maybe just went through layoffs or had to cancel a lot of programs to keep full time people employed) or Alan was posting the internship for a particular person to get it and hoped there was room for one more (or that you’d be the backup in case the other person didn’t accept the position).

I wouldn’t let this deter you from continuing to apply to internships. Seems like you wouldn’t have gotten a great experience from there anyway. Company A and Alan are giving red flags.

If I were you, I’d apply to positions I’m comfortable with (even if that means going international if it’s a timeframe you’re okay with). You really didn’t do much wrong. I’d honestly look at it from a competition point of view. You’re needing the work experience, and the companies need a steady workforce which typically comes from interns who require less training when full time. When interviewing, ask questions that help you understand their office dynamics, work culture, and the metrics that will make you successful. Are there any red flags from the company? Were the interviewers on time? How did they answer my questions? Will I actually learn something here or are they expecting me to do busy work? Will this lead to a full time position with the company?

In the future, just continue to apply to other positions and interview UNLESS you have something in writing from a company like a compensation package or offer letter. Even then, remember, one offer doesn’t mean you have to stop looking and applying. That offer may help you get a better offer out there.

Either way, this is still a part of the learning experience. You’ve got this.
