Had a call with a HR, then a consultant. Both are nice people. The 2nd round was a shared screen SQL interview. The SQL questions were easy~medium, but they only gave me 20 mins to complete 4 questions, each question had a few tables, eg, the 1st questions had 4 tables, and I spent the majority of time to understand the relationships between them in order to join them, and this is exactly the most difficult part, the SQL test isn't testing on your ability to solve problems but rather if you can read the questions fast and understand the data structure, overall it's a speed test.
