Psychometric testing at interview

[lucky24]

I have an interview coming up and i will have psychometric tests too. Any advice or any websites you know of that have example tests for me to try for free.

Thanks

is it myers briggs? not sure you can practise.... or maybe that is not what a psychometric test is. there's no right or wrong personality type.
what's the job? some of the personality types are named after jobs. The carer, The mechanic for example.

Thanks for the reply. The interview is for a tax adviser. The tests i think will be aptitude tests and will be to show numeracy and verbal skills.
