Actually you could look at just one of the slabs, since they are identical.
Dividing area by volume doesn't make sense. I think you are calculating the percent of faces that are colored. If I did the math right, that's a bit over 36%

However, it should ask what is the probability of ordering *exactly* 2 egg sandwiches, or you should increase the answer for the possibility that they order 3 egg sandwiches.
exactly.

Then Multiply by the number of faces (6) per 1x1x1 cube to get the expected blue faces per piece.

So what is the theory on being interviewed first vs last, etc?

Because I think that my interview was first because he told me that several people will be interviewed next week and a decision will come at the end of next week or early week after.

Also, suppose that there are only 5 interviews, of these 5, how many do you think will make it to the onsite?

I checked the glassdoor posting for this job, as well as the linkedin posting for the job. They are both closed. According to linkedin, only 7 applications were submitted for this job. I assume glassdoor would be higher.

So this is weird, why would they close their ads before someone is hired? There is no reason to assume that the current pool of candidates remaining in play will get hired.

So, there were 2 puzzles/brain teasers. I was slow to correctly answer one of them, and he guided me for the other one. Both were rather simple if there wasn't the stress and pressure of some guy on the other line waiting for an answer. Overall, I think I passed but did not ace it. So now it is up to how well the other guys will do. I think my chances are slightly over 50% if the decision is made only based on this phone interview, and perhaps slightly over 70% if the decision is made based on this interview as well as the results of the first round 5 hour code challenge.

Lasted slightly more than the max allotted time of 90 minutes, so I assume that's a good sign. Because he waited for the actual interview, where I answered his questions, was over before he went on to tell me more about the company and role. So the fact that he spent the time to give me this information means that I am still in play. Because if I was cut, then there is no point in extending the length of the interview.

Having been at the other end of a lot of interviews, I think you are overthinking this.

The order of the interviews is usually random, in my experience. Some admin is tadked with setting them up, and is given an unranked list of interviewees and interviewers.

When I interview, either the time needs to be precise, because the person is moving from interview to interview, or it doesn't. If it needs to be precise, I make sure to finish everything on time, and stretch out even there most painful interview to match the allotted time. If I don't have hard constraints on the end, I just take as long as it takes to get through my list. That can be a bit more or less than the allotted time. If you had a few more questions than I budgeted time for, or if you took a bit longer answering questions, I would still answer your questions.

And people have mixed opinions on the value of brain teaser questions, including the people who ask them. I've never asked them (it's uncommon in actuarial interviews) but I have a lot of friends in computer science, and they ask them. Just last week, a woman told me, "I used to think these questions were total bullshit, until I started asking them. Now I feel I sometimes learn something. Some people give really weird answers. Like the guy I talked to last week who refused to answer. 'i don't do brain teasers', he said. 'it's okay, I'll walk you through it'. 'no, I don't do that.'... So, what else won't he do? What if I give him a task at work that he doesn't like?"

I'm sure some interviewers take them more seriously than she does. But she asks them.

Anyway, good luck, but don't stress too much trying to read info into a pattern that may not mean anything.

If they don't like the candidates, they'll re-open it. But, for now, they think at least one of the candidates will be good enough and they don't want to be distracted by new applicants continuing to come in.

Yeah, I meant to say this, too.

Interviewing is expensive. And it takes time to set things up... during which existing candidates might find other jobs and leave the pool. They don't want to start over unless they feel they need to.

Fixed.

The only time I've seen (or at least have been told) of an order is I've been told that recruiters will try to get the ones they think are best to be first or last. If you throw in a rock star first, the other interviews may not happen. And if you throw them in last, the company has become so desperate for a winner that they get really excited. Even when somebody is trying to do that, there's often too many logistical hurdles to really make that happen.

I am going to hold onto your suggestion though. "Oh, I don't answer questions I don't like. Next!"
