I live when we are emailed "anonymous" surveys with a query string. It's even better when they are engineering specific surveys because at that point you have to question if they even think you can do the job if they thought they could get blatant tracking like that past any engineer

I saw such everytime too. These tracking params are to guarantee that the survey is filled only once by a person. But tracking is possible if email and the survey match is stored somewhere. It is all up to trust.

I've seen anonymous surveys that ask for the team you're on. Way to narrow down the possibilities management.

My favorite is where there is a remote team and it asked for team and location. That pretty much uniquely identified everyone. I made sure to give stellar reviews and praise for all things there :-)
