I think I'm picking up that your model of how a typical technical interview is structured is different from what the other commenters have in mind.

It sounds to me like you view the technical interview as being split into a high-level whiteboarding phase followed by a separate coding test that is not done on the whiteboard.

In every interview I've had that involved coding and a whiteboard, I was expected to do everything on the whiteboard, from drawing diagrams and working through test cases to writing the actual code under evaluation, all in front of the interviewer.

Under this (very common) interview system, there is no "other piece" for whiteboarding to be more or less stressful than - it's embedded into the entire interview! (Yes, there are other interviews throughout the day that might only involve block diagrams or ask behavioral questions with no coding whatsoever, but I don't think that's what most people have in mind when they're told to prepare for an algorithmic whiteboard interview).

I think the interview process would be a lot better if it started with a no-coding-required whiteboard collaboration phase, followed by coding solo, and then ending with a mini code-review on the whiteboard. This is similar to the private technical interview procedure described in the paper.

As to your other question, I'm not sure why you seem so dead-set against the idea that performing analytical tasks while being evaluated in real-time would be harder than doing so under normal conditions. That's what this paper set out to investigate.

I have never experienced such an interview, both when I am the interviewer and the interviewee, and I've been thru the entire process at multiple FAANGs. What you describe - literally coding on a whiteboard - is a far cry from whiteboarding a problem in my mind, this is a fair point

The entire interview has this elevated difficulty. You are constantly being judged and evaluated over the course of the interview. I have consistently asked for people to clarify why the Whiteboard part is elevated over any other technical portion in how stressful it is and how much that impacts performance, and I mostly have been attacked with strawmen. I appreciate your good-faith argument here, and certainly agree with you that conducting an entire interview including coding with a pen instead of a keyboard is a braindead practice. I will be more explicit of my assumptions next time as I would not have anticipated entire interviews to be conducted on whiteboards when you are trying to also find people who can code. I would expect what I've seen, which is that you use multiple different evaluation techniques across different scenarios and levels of interactivity and then you evaluate the tradespace, in which the whiteboard & collaborative time gives valuable data on how personality interop would work with your team.

I've been through the all-day on-site interview at two FAANGs and every coding interview involved me standing at the whiteboard for the entire interview. As the saying goes, data is not the plural form of anecdote, but it's certainly common enough as a format that it has to be considered when discussing whiteboard interviews.

I agree that the entire interview has elevated difficulty, but which aspects are intrinsic / essential and which parts could we remove with minimal impact to the effectiveness of the interview?

For example, we both seem to be in agreement that writing code with a pen makes the whole interview harder without facilitating what we usually want to measure - the candidate's ability to reason about complex problems and write good code to solve those problems.

From the findings in the paper, just having a proctor in the room is correlated with the candidates performing worse on the programming task (as measured by writing code that passes the test cases). I'm sure there are benefits to being able to observe the candidate directly, but those benefits should be weighed against the drawbacks and evaluated in light of whether or not it's really a net positive, regardless of whether the interview process as a whole will still be stressful in other ways.
