I’ve had a few 1.5 to 2 year stints and I get asked about it all the time. Certainly there are employers that don’t want to see that, though I’m sort of at a crossroads after 6 years in tech where I’ve realized part of the itch to move was less about money and a general dissatisfaction with a traditional 9-5, so I’ve since moved on from it and working on my own projects at the moment.
