Insource (UK) interview questions

During 2016, I attended an interview with Insource after going through an awful, disorganised recruitment agency. During the interview, I was asked personal questions which I didn't want to answer. To give some examples, she wanted to know the name and job title of my former manager and colleagues, my previous salary, etc. Of course, the interview was supposed to be about ME not about others, so such questions were completely irrelevant. Also, she lacked the basic understanding that one should not disclose details of past colleagues without permission from them. Such questions made me wonder if they wanted to cheekily contact my former employer without my permission. The disorganised agency failed to notify me of my application, forcing me to continuously chase them. The consultant I had to deal with was so disinterested that he had no idea why my application was unsuccessful, so I waited for him to check his emails before he said I was deemed "unprofessional" because I didn't drive! How silly is that! One's professionalism should not be judged based on whether you can drive, especially by a mere stranger incognisant of OTHER, more applicable measures of professionalism! Not a pleasant experience.
