I'd say that approach sounds quite risky.My suggestion would be to keep applying and not to hand in your notice until you have a confirmed offer. You could try to negotiate a start date 4 weeks ahead of when you will have finished your current role, allowing you to travel safe in the knowledge a new job awaits your return. Your firm may also let you leave/put you on gardening leave before the 2 months is out and that, combined with any spare annual leave you have left could provide the gap you're looking for.If you hand in your notice now, and don't secure a job before you want to travel, it may sour your travel experience and the temp job may become a lot longer than you were first hoping for.It may be boring where you are, but it's solid experience for the CV and shouldn't hold you back from the type of consulting roles you're after.Good luck
