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 respostas

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) Menos

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. :) Menos

It was positive experience. People were nice. Like craft demo which help to have discussion with team instead of traditional interview structure.

What is "void" and how is it used.

2 respostas

"Void" is an absence of something. It is used to represent a lack of parameters, returns, or defined type. Menos

In most programming languages, the "void" keyword means a lack of returned value. Menos

The 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 respostas

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. Menos

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 Menos

Most of them are on my skills, experience and process.

2 respostas

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 Menos

How would you access a linked list node at some arbitrary position 'n' in C++?

2 respostas

Because each node contains a pointer to the next node, you would follow node 1 -> node 2 -> ... -> node n. Menos

Hi I too am interviewing for a similar position at I believe the same location, so could you please tell me how your negotiation process went? Thanks! Menos
