Professional but lengthy due to how thorough it was. If you do well on the initial screening, you will be invited to a second part. The initial screening consists of a spelling test and reading test or critical thinking test, altogether this lasts about 1 hour. The second screening involves another 1-3 hours where you practice some of the programs they offer and complete a formal interview. They give you feedback on how you're doing as you go and see if you can pick up on the programs quickly. The interview itself included mostly basic questions like how to motivate students and what would you do if you were running late.
