The first phone stage involved a SQL database design question. I needed to be familiar with relational data modeling and design, as well as SQL select, where, and join clauses, and join tables (and modeling around JOINs; one-to-many and many-yo-many relationships). The second phone round was more coding / algorithmic, but still did not involve any actual writing of code or using a text editor, just the phone. Unfortunately I do not remember the exact question, but it involved the Levenshtein distance (look it up) and strings. the virtual on-site involved video calls and sometimes text editors and writing code. a total of 5 rounds, I remember at least 2 algorithmic / leetcode style sessions, and 2 system design sessions. the algorithmic questions were equivalent to leetcode easy and medium. I specifically remember one problem involving "balance parantheses". If you google that, you will find it on leetcode. One of the system design sessions involved designing a feature flag service with a SQL DB. It was heavy on the DB design. I unfortunately do not remember the second, but it was more than one question unlike the first one.

Questions segmented around general problem solving skills, whiteboarding, coding problems, and general software design. The questions asked were more focused on determining general aptitude and problem solving vs. specific knowledge and memorization of things like data structures and algorithms.
