Thanks so much! Since I've posted, things have evolved:
I interviewed for a graphics biz development (GBD) position within a sister company (which I'm pretty confident with doing, wouldn't need to change much, just move buildings, keep my laptop), most likely a 30-40% pay cut, while being offered other interviews with some good companies, but have about 48 hrs to figure out my plan.
I am finding talking to other companies looking for a UI/UX Designer are asking to do CSS/HTML and I feel very junior and inexperienced there, other than doing some training with it years ago. I will be taking action to learn as much as possible that I can with all of it. Thanks for the your extra input, Natalie! I've done a lot of Photoshop/Illustrator, etc., coming up with the design, doing research, etc., then someone else has previously been doing any/all of the coding.
My dilemma to decide in the next 24-48 hrs:
1) Take the more-than-likely (and easy job to do...one more interview with that tomorrow) GBD position, continue to train as much as I can for a few months with CSS/HTML, Bootstrap, Angular, etc., to feel more comfortable, and possibly risk getting out of the my UI/UX career?
Whether it's a go or not, the company is seeing if they would be able to accommodate getting a little closer to not cutting my salary as much (but not determined yet)
2) Still interview with other companies for around my current salary and risk showing up that I am not up to remembering a lot of CSS, where to start again, if that is the expectation?
I've had one already send me a simple test and I know it would take me longer to figure out and send back, but would they also be expecting more coding? Wasn't my original impression speaking with one of the designers, but it must be an expectation, have been sent a simple test.
3) Continue interviewing with my current skill set, just letting them now I can do small tweaking with current CSS/HTML using Firebug, etc., but am more in the are with coming up with what something could look like for with wireframes, design mockup with Photoshop/Illustrator/Omnigraffle, etc., supporting research.
Thanks again for all of your input!
