I agree with googling stuff but this gives me anxiety, even though I can create relational databases, use ORM/stored procedures/queries, write web apps, deploy to IIS/Docker. I still worry about looking for the next gig. I did write a complete mission critical solution for a mid-size business, used by 100+ employees but then I am asked about algorithms and I could answer 3 years ago but now I would get stuck on it.

Also, when I interviewed a year ago I was asked to find if something is a palindrome. This is programming 101 and it caught me off-guard. I got so used to all the methods available in C#, that going back to pen/paper and writing a simple for loop felt odd.
