Note that upper management is also interviewed in such a fashion, except with night vision cameras and the entire board crammed into a tiny security cupboard near the elevators. Any candidate caught trying to hide the existence of the IKEA dresser entirely is immediately hired once they have successfully gaslighted the interviewer.
We place the candidate in a room with a large whiteboard for 15 minutes alone with the lights off. I then walk in with a 6 piece dresser [1] from IKEA (obviously keeping the lights out). I explain to the prospect that this particular dresser is missing one piece - BUT we need the dresser assembled then disassembled and placed back into the box [without anyone seeing]. More than HALF the candidates become violent and demand to see my github account - some even suggest I have a mental issue. I am often able to calm the candidate down - this way we can get into the REAL debate: KOPPANG vs MALMs. Any candidate caught assembling the IKEA dresser is quickly dismissed out of spite. This technique is from Boz at facebook - it is how all* senior principle engineers are screened at FB and the reason everyone codes PHP (but swears they do not).
HR has complained that my techinques are "ridiculous" or borderline illegal - but so far my successful candidates perform, tend to have a solid grasp of typescript and quickly move into senior management.
