Select Legal Systems interview questions

This was the stage before interview which involved completing an exam within 2 hours. The exam contained very tricky maths questions which were difficult to work out as there was a lot of staff chatting and laughing in the room behind me, as well as various beeps from door card readers. The exam was poorly written, and a lot of the reference images were of poor quality so some questions were ambiguous. I never received a follow up call or email regarding this position which was especially disappointing considering I had invested 2 hours of my life to their exam. The least a company can do is send a follow up communication indicating whether or not a person had been successful. Very poor experience.
