There are 5 holes in a line, and there is a rat in one of it. Each turn the rat will move either left or right, but never stay in the same hole, and each turn you can check one hole. The holes are in a line so when the rat reach one end, it must move back in the next turn. What is your strategy to catch that rat?

start with middle move to 2nd and check twice and move to 3rd and then 4th and check 4th twice.. right? OR you start anywhere just move sequentially and check 2nd and 4th place twice Menos

middle to 2nd not needed
↳
Keep checking middle one, worst case delay is 4 check, and you should find it by then!! Menos

There's a lot of elements to typically cover in these questions, clarifications, scoping, making sure you're answering the actual question the interviewer is looking for you to answer, etc. Could be worth doing a mock interview with one of the Prepfully Arm Graduate Hardware Engineer experts... they've worked in the role so they clearly know how to get through the interview. prepfully.com/practice-interviews Menos

Q: How to multiply a number by 2? by 7? by 14?

Q: How to implement a 3-bit LFSR and build your output logic with it? If there is some brief state '111' that only lasts a really short time, what is the most possible reason it would be? When is it most likely to happen? How to amend this circuit?
1 respuestas↳
A: With hints, I concluded that there may be glitches in the output logic (a and gate). i.e. each d type does not update their values simultaneously. To fix this, just have an extra flip flop at the output. Menos
Two questions regarding MOSFETs, 1. The first question was to identify a MOSFET circuit, 2. The Second was to explain the difference between the parameters of two of the MOSFET devices in the circuit. 3. The third question was to write down sample code for a scenario.

I pretty much nailed the first but screwed up the second only to realise the correct answer after i left. For the third question, I can't remember the actual question or the answer i gave. Menos
