I thought it was strange that the interviewers were SO impressed that Alex took a commission only job at a young age. The way I see it is that a young person has the least to lose by taking a commission only job, because
1. The young person doesn't have a family to support, mortgage payments to make and can fall back on their parents for a home if it goes wrong.
2. The young person would only be on a low or moderate salary in a job with a guaranteed salary so why not take the risk and go for the chance of earning more than that?
3. There is far less stigma attached to a young person going out and looking for another job; if the commission only one went tits up then the young person would still be able to get on a graduate scheme with a different company.
Nothing to lose!
It is impressive that Alex took a commission only job, but not THAT impressive. An older person with several kids, a mortgage, loans, etc. taking that kind of job, that's what shows balls.
