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.
