guys, for IT/software engineering interview..
just wondering did any of you guys come across this situation. i have requested to attend an interview and there will have 3 technical tests; sql, unix and c. but i have a good c++ background, don't hv any experience in sql and unix. the hr know about it but she asked me to try my best for the 2 tests. i total in shock, i know we should prepare well for the technical side, but no for a new skills? i'm trying to learn from the basic, but there's quite a lot things need to learn for sql and unix.. any advice for this situation? thanks...

thanks guys for all the advice.. i guess i need to pick up both of them as many as possible before the interview.
