1h interview
I was asked: https://leetcode.com/problems/basic-calculator-ii/
with a

followup https://leetcode.com/problems/basic-calculator-iii

I did the first problem quickly but messed up the if statement, so it took me 15min to figure out my mistake...
Was then asked to "pseudo/skeleton code" the 2nd question since I only had 10 minutes left. (I said to use recursion with the 1st problem\'s function, but i think they were expecting a stack solution like in the editorial...)

I don\'t think it will be enough to pass tbh, but will update when I hear back results.

Update:
I moved on to onsite
