Phone Screen (Nicest HR person), Technical Interview (Leetcode Easy), ANOTHER Technical Interview (Leetcode LOL (Easy) and SQL)
After the HR screen, I was interviewed by an engineer. I was asked the valid parenthesis problem from leetcode. I solved it in the most efficient way, but was told that my solution was O(n^2) which was preposterous because i can see my time complexity in leetcode and it beat 90%+ of the submissions. He was almost a new grad(1yr exp), but was a manager......... moving on, he later realized it and he scheduled another tech screen.
Another new grad-ish turned manager way too soon. First question fizz buzz lol. Second question, design a MySQL schema, so, I designed an elaborate schema that allowed them to obtain unstructured data AND structured data, but that was waaaay too much for her to understand(she assumed I did it wrong? idk), so, I did it in the most basic way, but couldn't remember the MySQL commands for averaging stuff (probably just AVG or something), so, I loaded the information into my python (using a MySQL cursor)code and gave her the answer. She tried correcting my python code, but then she realized it was fine. Rejection the following week. Please have more competent engineers do the interviews.
