I worked at PwC full-time
Variety of work and training
Too much focus on minimising costs
I applied online. The process took 2 weeks. I interviewed at PwC in March 2016.
Make sure you know what you expect/ want from the internship (how will this further your career/life). Be able to justify your decision to apply. Highlight (with your CV) what kind of skills you gained from previous experience and explain how you can use them to contribute to the team.
Process was fast, people I talked to friendly but professional. They appeared kind of distant at first but got really enthusiastic and warm later on.
