Rest

I'm currently working as a software developer at a company for 3 years now. I've worked with REST APIs, built microservices, made important contributions to pretty much all codebases. I also have a DevOps role and have worked with Kubernetes, CI/CD, observability, resource management, very backend stuff. I have been praised by my higher ups for my work multiple times so I consider myself a decent developer Recently I've been thinking of moving on to explore other industries. I decided to do some leetcode problems to kind of prepare for the inevitable during an interview. Holy fuck, I wanna kms. I can't even finish easy problems a lot of the time. I work with complex APIs, distributed systems in prod environments... And I'm struggling HARD to merge two sorted linked lists. I'm starting to doubt my skills as a developer lol. I feel like these types of questions used to be so much easier in university. If I get asked to solve a problem like this at an interview I'm definitely going to crash and burn spectacularly Please tell me it gets better lmao
