I applied for a position and was invited to an interview.
The position does appeal to me. However, after reading the ad again in detail, I see they expect the person to have a different profile than mine.
I didn't lie in my CV and I included quite detailed information on my previous positions as well as projects in it. I assume they did read my CV, so it's not clear to me why they invited me. It's a very competitive field and many candidates fulfill the conditions.
There are 3 main areas of responsibility the person will be working on. I know two of them, but nothing about the third one.
I tried to acquire the missing skills quickly but that's not really possible and I wouldn't like to waste a week or more preparing just for this one interview given the probability they'll not want a person without this experience.
How should I approach that during the interview ("sell it")? Should I be assertive about not having experience in one of the fields they expect experience in and stress expertise in other fields not mentioned in the ad? What are other options? Can I do anything to increase my chances of getting the job? I want it, but don't fulfill the conditions.
It's not an entry-level position. I fulfill the requirements concerning the length of experience, just not expertise in one of 3 fields, but have other experience not mentioned in the ad.
