CodeScience Quality Assurance Analyst interview questions

I applied online and got an interview request 2 days later. I had a screener (video call) with a recruiter 2 days after that. The first negative experience was when the recruiter rescheduled the interview a couple hours before it was to start, moving it later in the day. I had plans that I ended up canceling to accommodate this new time. The conversation was pleasant and consisted of standard questions: "Tell me about yourself...", "What do you know about CodeScience", etc. It ended on a good note and I was told they'd get back to me in a few days. A week later I got an email from the recruiter stating hiring had "hit a bump and [they] aren't moving as fast as [they] usually do." Essentially, hiring for the position had been put on hold for some reason, but they'd keep my application for when they start back up again. Three days after I received that email, I got a rejection email. Strange and almost dishonest if you ask me, since I had just been told they weren't hiring right now. Oh well.
