took the dlr BU assessment for THY on 31th of august. I can say that, it really varies from company to company. we had only 1 day of testing from 8:00 a.m to 6:00 p.m. had the regular tests; physics, maths, english and aptitude tests consisting concentration, spatial orientation, cube rotation, running memory span, visual memory and perceptual speed. all went pretty smooth for me until the very final 5 to 10 secs. the final task of MIC was already not going well for me (having deviations like 5-10 degrees), in addition a little! distraction made it go worse.
all in all I want to say I'm hopeful and the real challenge will be in the interview.
