How many race heats are needed to find the 3 fastest pinewood derby cars out of a field of 8, if only 4 cars can run at a time (assuming that every car will always run the way/speed and each lane is exactly equivalent)?
8 réponses↳
so is the answer 4 heat 1 (first 4 car) + 1 (4 second set) + 1( Top 2 from first + Top 2 from second set) + 1 (3 car heat among the 3rd placed car) Moins
↳
Only two races of four cars in each. Get the times of all cars and sort them. You don't need any more races because the times will be the same in subsequent races. :) Moins

4 if we cant measure time

What is "void" and how is it used.
2 réponsesThe most challenging (and interesting) question was about a strategy for finding signal in a noisy and poorly understood data set. Asking a software engineer a data science question really stretches the mental muscles.
2 réponses↳
Challenging yes. But not necessarily in a good way. Most software engineers do NOT have the training to properly address this question. It requires a background in "data science" or signal processing. Unless the position interviewed for required these skills/background also, I would say the question was highly inappropriate. Moins

There's quite an extended back and forth in actual interviews for questions like this, so nothing quite like real practice. The Prepfully Intuit Staff Software Engineer experts have actually worked in this role, so they're able to do an honest-to-God accurate mock, which really puts you through the paces. prepfully.com/practice-interviews Moins
Most of them are on my skills, experience and process.

very good

In these sorts of interviews you really need to drill down and understand what the interviewer is looking for. A good way to simulate a real interview experience is to do a mock with one of the Sandisk Staff Software Engineer experts on Prepfully, rated super strongly on TrustPilot... prepfully.com/practice-interviews Moins
