Houzz Sales Representative interview questions

4 stage interview process, awful interview! the lady that did my Skype interview was so unprofessional to say the least, didn't even show up for the first interview and then when it came to my second interview she kept asking about my previous history in sales? Mind you, the job spec did say "no sales experience required". She was a French speaker and didn't really understand English properly so there definitely was a communication barrier between us! Lastly, not to disrespect but for someone who is conducting interviews in English with a very poor level of English is concerning and when she didn't quite understand my responses to the question she would act quite rude and cocky? So to summarise, waste of time, unprofessional and a communication barrier.
