In 1995, I was approached by two classmates in college. They, apparently, had started a company, and were considering offering me a job as the lead developer. No doubt, I was fascinated. But then, one of them asked me if I was familiar enough with the Motorola (later Freescale) 6805 processor family. I wasn't. The most accurate answer at that point was "no." However, I gave a different answer.

My answer was:

"if you are asking me this question today, the answer is 'no.' However, if you ask me the same question tomorrow, my answer would be 'yes'."

They took the bait. Although they couldn't meet the following day, we scheduled another meeting for the day after that. I had 48 hours to study. I went straight to the college library, and found a few books about the Motorola 6805 processor family. I knew other processors, so it was really just a matter of learning the specifics of this one, and how it was different than the others. The Internet was not as pervasive as it is today, so there was nothing useful there. Nevertheless, I spent the next 48 hours studying "enough to be dangerous." To the point that if I had to start a project using the 6805 processor the following day--I could.

We live in a word of specialization. Jobs require specific knowledge and experience. If you don't have the right knowledge, you will be passed on for hiring.

However, companies also look for creative people. Creative people are curious, learn fast, and embrace challenges.

So, there is a good probability that during your interview you will be asked about something that you don't know, or at least not know enough to qualify for the proposed job. You have three options. Say "yes" and lie. Not a good option, as it reflects badly on your character and you will not recover from this. Nor will you get away with it. Say "no," and you may not qualify for the job. Say "if you ask me today, the answer is 'no,' but if you ask me tomorrow the answer would be 'yes'," and you show that you are creative, curious, and serious candidate. Of course, then you have to actually study. Ask yourself: what is the level to which they would expect me to know this by tomorrow? Then learn a little more than that.

And this might just get you the job. Just like it did for me in 1995.
