Linear Graduate Trainee Sales Marketing Assistant interview questions

I was invited to two interviews. During the interviews they offerd two payment models one was a capped monthly wage and the other was a 100% commission based uncapped salary. During the interviews felt like they were pushing me to choose their 100% commission based salary. I told them that I would prefer the base salary over the commissions. I did not revive an offer, I am not sure if this was due to me not wanting the commission based salary, however the whole process seemed a bit sketchy and I did not read the best reviews about the company online.
