I got a letter from a company saying that they found my profile on a careerdatabase(?) and are really interested in having a talk with me.
I found out that the company itself is active in various really different fields. For example they themself are conveying jobs in tehir own database and offering it as service while they are also known for selling insurances.
Since I'm looking for a position as software developer and the phonenumber they asked me to call is located where the office of their IT seems to be located, I'm assuming they are not trying to to convey me but hire me for themselves.
Anyways here is now my problem:
When I called them yesterday, I got told that the responsible person is not in house for the whole week and they asked me to send them an application within this week so that it speeds up the process as soon the responsible person is available again next week.
But I have no idea what to write into my covering letter. Usually I write in why I think I'm the best fit for the position and what I made before that makes me proficient in what they do, but here I have no idea at all.
I can't get any idea what their IT might be responsible for since the company is active in so many different fields and I also have no idea which of my skills made them get interested in me.
So how should I design my apllication/convering letter in a situation like this?
