Somewhat fine, but I had a problem with last-minute rescheduling.

The interview was rescheduled twice right before the original time, and I was not consulted about the new time.

Then, halfway through the full loop, my interviews were canceled without any word or reason.

The HR person said they wanted to move forward with other candidates, but not until the day after, wasting my time.

All in all, the personnel was good, but the recruiter was very sloppy.

How would you design a real-time chat application?
