Upskilling or industry switch?

I’m currently working as an MBD expert (AUTOSAR ASW development) in the automotive domain with nearly 9 years of experience. Lately, I feel my learning curve has stagnated, and I’m considering a switch. I’m in a dilemma: • Should I transition into a completely new domain/industry, since I’m not receiving many interview calls from automotive companies? • Or should I continue digging deeper into automotive technologies and aim to become a domain expert/master? In either case, I would really appreciate suggestions on which skills I should focus on to improve my job opportunities. Thanks in advance for your guidance!
