Alkali Scientific interview questions

Great interview process. Very friendly, and straight to the points. Discussed all topics and had all questions answered. Felt important at first interview. Have had 0 complaints about the hiring process at any point in time.

A series of interviews, & during the first interview they stated salary would be 30K/annum + commissions, then during the final interview the company asked the same ?'s, flip flops and states the salary is either straight commission or salary plus commission. Further, the company didn't have the courtesy to notify me I wasn't chosen after wasting 3 hrs of my time. Very unprofessional!
