Stuck in a rut at work? Sure you deserve promotion but unsure how to build a case for more money and power? Or have a couple of nightmare interviews left you in need of a pep talk? We can help.   This week we do what your school careers adviser never did, taking through the best (and worst) practice to ace interviews and how to avoid common pitfalls when trying to get promoted.    Laura and Sam hear from a career fairy godmother who builds successful candidates from the bottom up, and grill their own boss to find out the one thing that will never get you hired.   To get in touch, email moneypodcast@telegraph.co.uk or phone our voicemail number at 07523 039447.   And visit www.telegraph.co.uk/moneypodcast for more.
