No phone interview straight to onsite then was told I'd hear back in a week. No communication thereafter. Honestly it was a major red flag that they didn't bother to give me a phone interview first and that I interviewed with people who were trying to be as mean/negative as possible

I got the first round trader test which was 30mins in length. I interviewed at their office. Most of the questions are probability questions and brainteasers. A pencil and scratch paper are allowed. They are looking at how you react when facing pressure, so just tell them about your thoughts when you cannot work out the problem. The interviewer was quite nice.
