As any recruitment job this isn't a 9-5, some nights you will stay until 7pm/8pm to get things done, but at the end of the day it's your own commission you are doing it for.
Like in any sales job with revenue targets, you are expected to hit certain criteria and KPIs but if you are hitting your target and doing well, you will not be 'told of' for sending 1 CV less than expected.
Just like the late hours, you are expected to develop yourself outside of work, whether that's listening to podcasts or reading up on your market - for me not a con, but just to highlight it is an around the clock job, just like you may be expected to answer calls and be available on your days off if you have certain processes happening or take calls out of hours to catch that candidate you always wanted.
It is a hard job and can be a rollercoaster of emotions, the incentives and nights out are there to reward the hard but rewarding work. But the people really do make it a great place to be and you can always relate to someone.
