If you think the new job has the potential to be more fulfilling and you are willing to take the gamble they work out in the future. I would say do it.
I took a job at my first start-up three years ago, where I actually took a pay cut. Partly because I didn’t see my role still being around much longer (I was right), and I was ready to finally try a privately owned company. So sick of the big corporate culture.
It has paid off so far. I have had many opportunities to advance and try different aspects of engineering and maintenance, including management. I also make +$25k more now than I did before changing jobs, and now work remotely.
Though the biggest thing for me has been being able to be proud of what I do and feel like I am making a difference. I worked in engineering mostly supporting oil and gas for over a decade, and am finally working in renewables and upcycling on some pretty cool technology I actually believe in.
I had also stayed in jobs that I grew to hate too long and literally almost died from it.
I would still ask for something more in the offer though. It sounds a bit too lateral of a move for taking the risk.
For most people that is definitely true. I however was a cashier for six years before graduating college and am at the very least just as fast. My problem is usually the scanner won’t keep up with me since there always seems to be a delay for the system to verify I have put the item in the bag before it lets me scan another.
