There are way too many variables to answer that. If its really important for the job or their is another candidate they like almost as much as you, then yes its possible. You just never know. I've lost jobs for things I didn't even remember coming up in the interview. That's why everyone hates doing them.
Okay, so here's what happened.
I had two rounds of interview, one with one person and one with another.
The first one went swimmingly well. Had a detailed and substantial answer for every question and I seemed like a good fit.
Second one was a bit awkward. I wasn't sure how much in depth I should repeat myself, and the rapport was not on the same level as with the first one. But what I think I truly fucked up is the "Do you have any questions" part. I knew that I was supposed to, so I picked one.
In my statement for what my long term plan is, I said I wanted to work for the company, before hopping off to grad school, before again hopping back into the company with more education that I could contribute more. Seemed like a good answer to me.
So I asked "How long would you want me to work for before I would go to graduate school". Because I had one specifically in mind. They work with many different companies, so I envisioned I would still work at the company part time as I got my education. Except that school is far away. I mean, I did have alternatives. I could work more from home, or maybe I'd just go to a different grad program closer to the company. I course corrected it, but it was too late.
She just gave an awkward look of "Well, I don't know, as most people don't do that. Most people work here part time while they study. We'll want someone with long term commitment to the company, so we'd have to see whats available"
Such a stupid, obvious red flag that I should have avoided. I don't know if I totally crashed and suck my ship here, but it is one huge and obvious blemish on an otherwise stellar interview at the one company I really, REALLY wanted to work at.
They told me they might contact me about job openings, but I should also make sure to stay in touch with them. What I had wanted to hear was "We'll find if we can fit you internally, or otherwise we'll find a place with one of our clients for you.", since that implied an intention to get me a job. I'm trying to be optimistic about it, but....well, goddammit.
