PDG Consulting Software Engineer interview questions

The interview process with PDG Consulting was like a poorly edited scene from HBO's Silicon Valley. After a phone screen and completing a Codility test, I was invited for an onsite interview at their office. Finding their office was quite difficult, given it was located on the top floor of a condo somewhere near Skid Row of Downtown LA and appears to have the same address as a barbershop located immediately downstairs. Inside of their office were 10 - 12 computers circled around a Lifetime table that is the exact same model used by the nice family that once sold tacos on the corner of 3rd and Serrano in Koreatown. Quite frankly, the work environment resembled the set of a movie depicting a tiny sweatshop. A civil engineer turned software engineer resembling Andrew Schulz grabbed a man resembling Christoper Khai's character from the 2006 comedy, Accepted. I was taken upstairs, where there was a smaller Lifetime table in front of a whiteboard. Outside sat a young woman who I can confidently identify as my recruiter given that I've been in correspondence with a young woman for weeks and she was the only woman present. I sat on the opposite end of the table in front of these two characters, who dived right into drilling me about my last internship experience. In spite of the numerous other relevant experiences listed on my resume, they were only interested in the last internship I completed. This would not have raised any red flags if this wasn't very lucidly the ONLY thing they were interested in. Their questions transitioned from wanting to understand what I did to a space of wanting to understand how I did what I did, with questions about code implementation/refactoring, where to acquire the relevant software, and other minute specifics. After 30 minutes of questioning me with regards to this internship experience, they then asked me to implement an algorithm for the recursive Fibonacci, which I did in about 2 minutes. I explained my solution and they seemed more than content with it, stating that my solution may be better than the one they already had in front of them. Prior to the interview, I was told I would be reimbursed for parking, but when I told them parking was $16 dollars, Schulz told me their maximum reimbursement amount for parking was $7 dollars. He went into a drawer, counted out $7 dollars in singles, and handed it to me with a smirk. I was then shown the door and told I would hear back in 3 - 4 weeks. I never heard back. I truly hope this fledgling group of mid-level programmers got all the information they wanted out of me and that they don't waste anyone else's time and gas money the way they wasted mine.
