I tried out for a group after the end of the first year of grad school that worked on the CMS detector at the LHC looking for SUSY signatures. The group was a well established group but felt super toxic: I attended a weekly meeting where the advisor demanded some analysis from a grad student and she literally froze up and started talking faster promising to finish it by the end of the week. As a part of the trying out period, they allowed us to skim one of their technical reports and they had I believe ~10+/-5 potential events matching their search for SUSY particles, this over the petabytes of data for a two or three years of the LHC runs at the time. At the time I really liked particle physics but I also liked essentially coding and thought I'd miss it, so I was conflicted. It didn't help this esteemed professor felt like such an jerk AND their search, despite all the sophistication of their search and the related physics chops, basically had a large "no" for an answer. I ended up chosing a smaller group doing computational laser-plasma physics. The CMS professor at the time retorted something along the lines of "someone shouldn't want to do particle physics and then do plasma physics, it's evidence that person isn't serious."

Fast forward 10 years or so and I haven't regretted that decision. Not only is my pay much better doing this sort of thing but I really did nope out at the right time. I mean, I felt so smug about the noble prize being won by the attosecond researchers, one of whom had an office down the hall from our group. The same grad student who decided to bear the brunt of the CMS prof at the time justified the dearth of working in the group (although perhaps not the abuse, I don't know) as it would be potential "noble prize winning research." I feel I made the right bet at the time and don't regret it.
