We're still stuck with doing them, unfortunately. It's a quick meeting with your TL towards the end of your 90 day probationary/learning period where we'll go over what you're doing well, what we think you need to focus on, and then we'll give you the opportunity to ask us any questions you may have. (example: training/learning gaps, cross-training opportunities, etc)
It's usually like a quick 5 minute sit down and then you'll be on your way. No big deal at all 🙂
Like they said above, there's a 99.99% chance that if they wanted to fire you for something you did in your 90 days, it would have probably already happened.
