They can act if your entire interview content is already online. Everyone knows the typical TMAAT and "what is your worst..." questions are coming and people already know their answers. As a result it is time to act because you don't want them to sound canned!Let's think about this for a minute. What would be easier for someone to "act" out an answer. A common straight forward question or one that throws someone off? Read what you wrote again, there's a reason for off the wall questions. Reactions tell alot.
I tried to wing them once and fell on my face. Why? Because it is purely a game. The fact that I can't come up with a "worst attribute" or "What do you dislike about X" that I can spin positively on the spot shouldn't be bad mark. They are seriously questions that are designed to get you in trouble.
I'm taking it you are/have been an interviewer. In all sincerity, what are "off the wall" questions, and what is the reason for them? Can you give me an example of an "OTW"? question? And the reaction(s) you are looking for that would be deemed positive or negative? If by "off the wall" you mean random, ad hoc questions, how do you measure answer response? Is it scientific, subjective, just kinda your gut feeling that particular day? I'm not trying to put you on the spot. I'm truly interested in how this process works... and if, in fact, it is really a process at all. The questions I find most useful (from both sides) are those that elicit real knowledge of stated experience. Instead of "Tell me about your international experience," better might be "When you flew to Peru with a stop in Mexico, what paperwork did you need with you?" Now you have a relevant, open-ended question with a measurable response while still providing an opportunity to get a sense of the candidate's skill as a raconteur.
I find it hard that they are purely scientific. Interviews are essentially a first impression and first impressions are wrong more often than they are right.
Heck, here is a study showing you have a better chance at a positive outcome just based on the time of day. Yes the study is of a parole board but ultimately it is the same thing. Take in a bunch of info on a person in a short period of time and make a judgment call. If you happen to interview just prior to lunch or the end of the day you will be less likely to get the job.
You are also less likely to get a job if the interviewers hired a lot of people prior to your interview.
Sadly the content of the interview means less than HR wants to admit.
