IBS occurs when the person interviewed knows the correct answer to a question, but gives an incorrect answer to the interviewer. IBS is a “performance under pressure” issue, familiar to a student who does well on homework problems, but gets similar problems wrong during an exam.

By analyzing recent attacks of IBS, I gained some understanding of causes, but I am still looking for preventive measures.

IBS usually occurs when the question is too simple, and seems to have at least two kinds of symptoms:

  1. Expecting a hard question, you subconsciously rule out the more obvious answers, which may actually be the correct ones. The answer you actually give seems illogical to the interviewer.

  1. The answer is so obvious, your mind says “done!” when you have not finished expressing the answer. During a recent attack, I drew a circuit with critical components missing. Despite of the interviewer asking another question about the circuit, I still did not observe the omission. The problem seems to be a disconnect between the mind, and the concrete world of paper, pen, and drawing.


Slow down, avoid answering right away. Repeat the question in the same words asked, then rephrase it.

After making the drawing, ask yourself if it is complete and corresponds to the question asked.

Answering quickly and correctly is the best, but if you are susceptible to IBS, then it is better to slow down.
