Dear Buzz!
I was wondering how sure you are that the same questions will be asked for the interview (and you have posted this across so many forums).
Please search on citehr first (not just the two questions that you have posted - but just glance through the material in this forum).
You are a fresher - so the interviewer will not expect answers that would be managed by experienced people. So - first, please see in your class notes what advantages these would provide and the disadvantages in implementing it. Rather than pointing out which is better, try seeing the limitations for each.
BSC - is really vast...
They might task you on what is performance management systems.
And as far as training and recruitment costs are considered - these are expenses that are made for acquiring and retaining talent.
Recruitment costs: Include the expenses on searching for the candidate (in posting ads, job boards, or consultants, their interview travel allowance, interviewer travel expenses if any...) In a nutshell - the cost involved in hiring the right talent.
Training costs: The expense involved in training for new skills, products, or software.
It can also cover a wider area like - in-house trainer cost, time spent - cost, etc.
I saw in a different forum you have mentioned that you are seeing various versions of calculating the costs - I suggest you to just see one, understand the basic concept, and be confident during the interview. Don't put everything in your head and be confused.
I was also overly "prepared" for my first interview and was - just like how you are now - pulling out all jargons and trying to make sure I know even the most difficult thing... It did not work out in my first interview... the question that GUY asked me was "tell me how to calculate wages, and explain about how to open a Provident fund..."
I was blinking, he embarrassed me - but today I feel like seeing that man and giving him a piece of my mind for asking a fresher that type of question! (so if you come across someone similar to this person - please know that he is not worth interviewing you)
The second one was successful - I was least prepared. I was asked about employee motivation.
Answer was: Simple - you pay him what he wants, you let him know that he is doing good, if he deviates you must be smart enough to point that out, and he should always think that he is working under the best boss he could ever have... all this to be professionally managed!
The reason why I told you so much was - an interview is not that difficult as you think. You just need to be smart and quick with your answers and, most importantly, have a good presence of mind - too much analysis can kill you!
Now get some good sleep! Good Night!
