Technical manager Interview Questions
When hiring a technical manager, an employer will look for candidates with the management skills and industry knowledge needed to oversee company projects that require members to have large amounts of technical knowledge, usually in the form of programming and software development. Some of the interview questions you may be asked will target your management experience and philosophy, while others will focus on your understanding of the technical processes you will be working with in the project.
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 *

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
Given a string like "I'm being interviewed by Amazon" implement a method that reverses the given string so that it looks like "Amazon by interviewed being I'm".

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
↳
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
↳
- 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
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
What is the difference between a risk and an issue?
4 Answers↳
An issue is an actual problem which is (negatively) impacting your project. A risk is an unknown or potential future event -- can have negative OR POSITIVE impact (yes!) and may or may not occur. Less
↳
The key difference is an “issue” already has occurred and a “risk” is a potential issue that may or may not happen and can impact the project positively or negatively. We plan in advance and work out mitigation plans for high-impact risks. For all issues at hand, we need to act immediately to resolve them. Less
↳
This is classic project management professional terminology, which I knew. But since I'm not a PMP I didn't know the precise definitions so I didn't try to bluff it. In the real world the two things are so different that you can't really point out what the differences are. I was left doing a goldfish impression - mouth opening & closing. 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).
