Advice Needed Please
I am a Design Verification Engineer who has been working for 8 years at a large aerospace company in the US. I did my undergrad at a top 3 public university in the US (3.5+ GPA), as well as my masters in CE. I had a 7-hour interview a few days ago for a Senior DV role, and I got wrecked. I got asked coding questions (LeetCode and similar) where usually I would just use ChatGPT for the code. Other questions were theoretical DSP concepts that I studied 10 years ago.
For the past two days, I've felt devastated. Even though this was my first interview in years, the questions they asked aren't really important on the job. I feel like staying 8 years at one company is too long, and my learning has stagnated significantly. However, I am also unsure of how to navigate this job market. After this interview, I feel like there was no need to go to a top university and study so hard if the barrier to changing jobs is that high. I’m in my early 30s and not sure how to take my career from here. Any advice on how to prepare or navigate this, especially from US citizens, would be much appreciated.
