Top Technical Manager Interview Questions & How To Answer

Here are three top technical manager machine operator interview questions and tips on how to answer them:

Question No. 1: Have you ever dealt with staff members who were resistant to new technology or technological processes? How did you handle the situation?

How to answer: A technical manager often introduces and rolls out new technology products and processes to an organisation's staff members, so it is important to know how to do this in a positive way. When answering this question, try to think about a specific situation in which you dealt with resistant staff and how you interacted with those individuals in a positive way. As you describe the situation, use the STAR method: situation, task, action, result. This question allows you to describe your problem-solving and communication skills.

Question No. 2: Describe your process for researching and implementing new technology.

How to answer: When answering a question about your process, consider a specific situation in which you researched and/or implemented a new technology in a previous role. Describe the steps you took and why you took each step, as well as the outcome of your research and rollout processes.

Question No. 3: How did the last company you worked for benefit from your technical expertise?

How to answer: Answering a question about your technical expertise allows you to elaborate on your technical skills and strengths and how they benefitted those around you in your previous role. Describe specific situations that highlight the importance of your work, such as new technologies that you implemented or rolled out that led to significant improvements or positive results.

* Given an array of numbers. Create another array that contains * the product of all the members in the array except the current * element. For example, if you have an array of 3 elements such as: * * A[0] = 2 * A[1] = 4 * A[2] = 6 * * Then the resulting array will be * B[0] = 24 * B[1] = 12 * B[2] = 8 *

public class GoogleInterviewQuestion { public int[] computeProds(int[] intArray) { int product = 1; int[] prods = new int[intArray.length]; for (int i = 0; i < intArray.length; i++) { product *= intArray[i]; } for (int i = 0; i < intArray.length; i++) { prods[i] = product / intArray[i]; } return prods; } public static void main (int argc, String argv[]) { GoogleInterviewQuestion giq = new GoogleInterviewQuestion(); int array[] = {2, 4, 6, 8, 10}; int prods[] = giq.computeProds(array); } Less

More than division by 0, it will fail if any element of original array is 0. All elements of resultant array will be 0? While one element dosent need to be 0. Less

Or even better: def ComputeProds(arr): return [reduce(lambda x,y: x*y, set(arr).difference([c])) for c in arr] Less

you have one giant cube made of 1000 small cubes(arranged them in 10x10x10) if you put the giant cube into the bucket that filled with water, then how many of small cubes are actually get wet?

8 Answers

488. 1000 - (8*8*8) = 488

correct answer is 488 : 2*[10*10 + 8*10 + 8*8] = 488 This accounts for including of cubes with sides viible on 2 or three flat surfaces and eliminates the repeats.. Less

Top and bottom faces: 10 * 10 * 2 = 200 The blocks along vertical edges = 4 * (10 - 2) = 32; -2 as the top of the line and the bottom of the line are already counted amongst the top and bottom faces. 4 inner faces = 4 * 8 * 8 = 256; 8 as these aren't yet counted amongst the top and bottom faces or the vertical edges. Total = 200 + 32 + 256 = 488. Less

What is the hardest thing in moving a team to Agile?

5 Answers

It's the people. Getting them to understand the Agile concept, then utilize it. Some developers never get "Fluid Requirements". They want final requirements and that's it. Less

- New team (everyone is still forming, norming, storming) so hard to estimate and collaborate - Distributed team members (works best if teams are collocated) - Strong, individual performers. Agile is about team work. - Not having a product owner - etc. Less

1. Communication. Frequent communication from the developers to ensure problems are raised and solved 2. Team needs to learn how to ship products with low-pri bugs Less

Estimate the number of spark plugs in the state of California.

5 Answers

In fact the number is much larger than that. The average number of sparks per vehicle (in CA) is probably closer to 5.5. Four-cylinder vehicles are the norm in Europe, but in the US is common to see a higher percentage of V6 and V8 engines. For every gas (not diesel, as noted previously) vehicle in CA, working or not, you could estimate ~5.5 sparks. In addition, you have to account for all stored (i.e. not necessarily installed in vehicles) sparks. So if there are, say, 20k car shops in CA and each of them holds 100 sparks in stock, that's another 2M sparks. How about motorbikes? Probably 2.5 sparks on average? Any spark factories in CA? Finished product would count too. How many unsold/retired vehicles? I'd say the final number is well north of 100M. Less

Cars, lawn mowers, edgers, and many other engines. Only going by cars is a huge underestimate. Less

This is a fermi question. assuming there is one sparkplug per vehicle, and the number of sparkplugs used in other machinary pales in comparision to the number of vehicles in california, then you just need to get the ball park figure for the number of vehicles.. here's my shot at it.. CA population is roughly 40 million. I would estimate roughly 1 car per family.. so lets say about 15-20 million cars in CA (taking into account children). so ball park figure of 20 million. lets add 10 million more for commercial vehicles, motorcycles,trailers etc.. . I would estimate a total of 30 million spark plugs in the state of California. Less

How would you explain story points to a team who's new to Agile/Scrum?

4 Answers

Time vs effort.. teams get hung up on time based estimates. And not about the amount of effort it's going to take to accomplish a task/user story. Less

It’s about demonstrating it to them and comparing the efficacy compare to other frameworks via dissecting a story vertically to the smallest size possible. Less

I said I would talk to them about t-shirt sizing and try several ways to help them understand that story estimation has little to nothing to do with time, rather effort. I also explained that this was a challenging topic for a new team. Less

A vaguest ion that was asked in a very general way, but which the interviewer clearly had specific answers he was looking for: "what are four components that are included in every specification doc". That sounded a lot like a thing you would find at Microsoft and similar large companies where process is more strictly defined. I answered poorly, I think, perhaps because I haven't worked with that kind of spec in a very long time, and not on any projects that worked out well. Smaller orgs/programs/projects (startups and incubators, for example, where the outcome is always in flux, as I am accustomed to working with) can have poor specs, specs that are centered on marketing, planning documents that are made up of wireframes and time-based stage gates. In any case, I choked a bit, and the interview kind of skated around and became more specific as we went along. I don't think that is inappropriate, though, because Amazon does value and expect the ability to deal with ambiguity.

"what are four components that are included in every specification doc" This question is insane, and I would hate getting an interviewer that asks such a question. Correct answer can be: "1. Title, 2. Author, 3. Requirements, 4. Version". If the title "requirements doc" is not there, maybe it is not a requirement doc. Specific sections are: http://en.wikipedia.org/wiki/Product_requirements_document Less

The toughest interviewer with the "4 components" question was a dev, in fact. The TPM screen was not so academic, more about challenges and solutions, philosophy, team fit, familiarity with the specific technology and business. That was definitely the screen that didn't go well, although he was wicked smart and wasn't just trying to mess with the candidate or anything. Less

Given two arrays find all the points of intersection between the (i.e. equal elements) and return them in an array.

4 Answers

traverse first array: O(n) put elements into hashtable: O(1) traverse through second array: O(m) check for existence of element in hashtable: O(1) if yes, add to resultant array. return resultant array So, final time complexity is O(n) Less

couple of solutions - sort the array (nlogn) complexity - browse with the smaller array and visit each of the bigger array and return if there is a match. Complexity (n square) thus not a good solution next solution - sort the arrays and remove duplicates (nlogn) - create a table, with the longer array - browse to the smaller array and update the count - Less

use a hashtable. O(n).
