I don't think these interviewers expect quicksort verbatim (though they usually don't ask for a run-of-the-mill algorithm).
They want to see your thought process as you tackle an unfamiliar problem. Do you think about the input and the end-goals explicitly? Do you consider multiple different ways of solving it, and cover pros/cons? Do you consider where issues may occur, and attempt to mitigate them? That's what they want to see.
OEMs (generally) eventually started making the power ports a replaceable part to make it a cheaply resolvable issue. Hopefully they will apply that wisdom to USB-3c ports on devices that use it exclusively for their power connection.
I will soon be working as a PM at one of the big tech companies as my first job.
I've gotten the gist of these lessons from a software engineering class, HN articles, and from my internship (at the same company), but I'm still not very confident about becoming a great PM. Can you recommend any books or resources that covers more of this kind of stuff?
He didn't seem to have a vision for tablets replacing pen/paper notebooks. The tech is here and prices are getting low (e.g. dell venue pro 8 with a stylus for ~$400); soon mainstream consumers will go fully digital and trash physical notebooks. Apple still can capture this opportunity, but they need to get past this idea that stylus==bad.
I'd guess the first company to get a 10" tablet with a good notebook application and stylus for under $300 will be the big winner in the classroom for the long run.
Surface Pro (or any windows tablet with a wacom-like stylus) with Onenote addresses all of these issues.
Especially since you can easily screengrab portions of the screen (e.g., a relevant theorem from a pdf) and 'print' anything to any onenote page, it's really clean and easy to get all relevant content in one place. It also makes your handwriting and printouts searchable. I also really like using the webcam to take pictures of whiteboards/lecture slides to annotate on top of (really helpful for 'old school' classes or Professors that don't share their slides).
