As a preface: I'm heavily on the spectrum, and so interviews are inherently difficult for me to begin with.
I applied for this job post-graduation and was offered an on-site without any sort of phone screen. I was extremely down on my luck with finding a job, and so I happily obliged. Well, about a week before the interview is scheduled to take place, the recruiter panicked and tried to contact me every way she could because she 'made a mistake' and thought I was still in school (yes, REALLY), and that I needed to contact her immediately and tell her what I've been doing since graduation. She accepted my reasoning, and the interview was still on.
I interviewed with three groups while there. Several people from the first group made me feel unwelcome. One girl asked about how I ended up on the educational path I did; I mentioned the fact that I went to a community college for my freshman and sophomore years, and she literally facepalmed and sighed heavily and started taking notes like I'd lied on my resume (as I only listed my bachelor's and master's degrees for relevancy).
After finishing my interview with the first group, the team lead escorted me to the next group. As we were walking between buildings, I remember inquiring with the team lead, 'Tell me about the ideal candidate you're hoping to hire.' She responded, 'We're looking for someone who can actually talk to people.' Of course, I was oblivious to what she was referring to, and I followed up with, 'Oh! I have lots of experience with talking to people, because I used to be a TA and taught a few classes!' to which she responds, 'Heheh... oh you seem so sure about that!' And hence each of the interviewers were probably relaying to her immediately after walking out of the room how poorly the interviews went.
Second group, the dudes seemed like he was just reading off a script and took no notes. With the second group was the lunch interview (which they say won't be on the record). They were with people who'd just recently graduated as well. I tried having casual conversation with them like they're expecting. But, at one point one of the guys flat out told me, 'Hey man, you should probably eat instead of talking.'
The third group was nice and I don't really have any qualms. They legitimately tried helping me out as if they REALLY wanted to give me the job, but unfortunately my interviewing skills didn't quite make the cut.
I was told upon leaving that I would hear back about any offers in about 2-3 months' time. Well, no. I heard back literally the next week that it was a No from all three groups. So I pretty much have a guarantee that I've been blacklisted from JHUAPL.
I have worked on my interviewing skills since then, and eventually found a job after about 2 years of unemployment, but the main point of my review is to highlight that YES, even though this is JHUAPL the interviewers can be rude. Even though I'm probably blacklisted because of the recruiter's mistake and bad interviews, this isn't a place I can foresee ever running back to.
