Excruciating. Made me feel guilty for not putting in enough effort in the assignment. Then asked me to redo the assignment "taking all the time I want". After slogging for 3 weeks, I had an interview, where two snobbish people came in, looked at the presentation, said that it was good, spent another 5 minutes asking me about my prior work and then dismissed me and closed the interview. I did not receive any respect nor regard. It felt like they needed the presentation and made me do it to use it somewhere else.
