Like everything in life, offers go much more smoothly if you prepare.    Smart candidates know that it's not just the salary figure that counts, and when they start asking questions, and your every answer is 'I'll have to ask HR' you start to feel stupid.  Here's a (probably not comprehensive) list of things you might be asked about;

*Salary review date and methodology
*Bonus and how it's calculated / when it's given
*Pension type and contribution
*Healthcare type and contribution
*Car allowances
*Gym membership
*Other benefits
*Relocation package (where appropriate)
*Golden hellos/handshakes
*Holiday entitlement and holiday year
*On site facilities
*Hours of work and flexitime methodologies
*Place of work (for those working on multiple sites)
*Training opportunities
*Nursery vouchers


Very smart candidates (and you only hire those right?) will also ask about start dates and what they can do to prepare themselves for the role. 

Can you add to this list?
