KPMG Director interview questions

Referred to HR by former colleague, which led to several calls, and invited onsite to VA for a one hour meeting. I should add that the Director that interviewed me was completely unprepared, asked ridiculous questions (technical questions without any context), and was not a subject matter expert at all. In addition, out of the 1 hour interview the interviewer was sending out emails and doing client work 70% of the time, which is a complete joke and very unprofessional. I almost walked out. I would definitely not interview with KPMG again, and felt they don't take the process seriously compared to other Big 4 even after I let the recruiter know who basically replied, "ok." What I found interesting was that the interviewer worked at my former company and I knew for a fact he got that job at KPMG not having the right level of experience to begin because I know his team and the type of work they do/don't do. To make matters worse, I flew to Arlington and booked a hotel and the company didn't reimburse me for travel expenses for almost 2 months. Perhaps others have a better experience, but at a Director level, it was not well handled and seemed liked no-one really cared.
