After leaving a certain well known tech company, I also wanted to reflect honestly on the experience of working there. I tried to be honest, in a blog post you can probably find, about the problems with the place as well as moments when I wasn't at my best and could've done better.
Later, when I decided to go back to work, a prospective boss found the post and basically didn't hire me over it.
In this case, I felt fine about it. I could stand by what I wrote, and this person's not getting it was a signal for me that he wouldn't be a great boss.
But if I had written a rant and dropped some f bombs, I might have felt more silly.
Great respect for Rachel, I love her blog and she's clearly an amazing person and I wouldn't presume to tell her what to do. But, other readers, you're not Rachel. Consider your actions.
