Questions and Ideas to Clem

Your job search engine is not very intuitive:
I just searched for jobs in London in last month and came up with zero!
Either you really have NO jobs in London, or, your search engine just dont work.
Of course it could be the User (Me) ?

simply put,
In 'Search Jobs For' I put nothing - I'm interested in all jobs.
In Location I put 'London' without quotes.
In Posted selected 'In Last Month'
button Search
zero jobs returned -

I think its unfair to tell you to DITCH this service, as its too soon, but I think you will find that Job serve has this service sewn up.

If you intend to continue perhaps you should specialise and promote Financial Jobs? though you could still keep general jobs on if it were next to zero costs.
