The first stage is HR Interview that lasts about 15 minutes. There are basic questions to describe your interest to the position and relevant professional experience. The second round is a test. The third round is about to come next week.

A lot of scenario based questions and a technical take-home assignment. Big red flag was that they refused to disclose the salary even after asking twice, once in the initial interview and again in the final interview. I've also heard that Meltwater underpays so that's most likely why, but extremely shady to go through a 3 stage interview process while refusing to even disclose a salary range.
