Our current assessment is about 4 hours and i think that's too long. When i was hired I remember multiple points where i seriously considered giving up. O can't help but think how many good people we lose to an excessive applicant process
Serious question, are you not also concerned about the poor quality of worker you might take on with a less rigorous process? I think I'd accept a few false negatives to avoid the hassle of false positives (in the UK at least, where employment law protects employees above all else and people can be very hard to get rid of if they want to be).
UK has trial periods too though, or? I've been in trial periods from 3 to 6 months, which is ample time to find out if the hire was successful. It's of course still very bad to fire someone during the trial period though (for both wasted effort and employee morale), but there is that option.
