First was a standard application screening, then a video interview with standard competency/motivational questions. You get a minute or so of preparation
Overall a standard modern interview process, not that different from other law firm interview processes
Other Trainee Solicitor interview reviews for Mayer Brown
Written test asking for various soft skills and then a virtual interview with pre recorded questions. Interview with partners after but did not make it to that stage of the recruitment process.
There are in total several rounds of interview or something. First is to fill in a form. The next is an aptitude test. After that is an interview. I did not go further after that
