I can honestly say the place I worked that had a probationary period had the most talented team of anywhere I have ever been, and I have worked with FAANG before, as well as unicorns. Like I said, it's not for everyone. A bad manager can ruin your experience anywhere and fire you regardless. That place was just very forthcoming about the fact that you need to demonstrate value if you want to keep your job.
