How many man hours would it take to clean every single window in London?24 Answers
10 minutes per 1 window
5 minutes in Total. Everybody should clean their own window same time
How long have you got?
It depends. How many single windows are there in London? Inside and outside? What's the average and mode window size? Do you want a range or an estimate based on the average window size?
The Windows would be all self cleaning
Thank you for the time, this job's not for me...
Based on London's population and an average time per window you could give a rough estimate. Each person has a home and a workplace (schools or other public institutions are also here). So I have 2 windows for me at home and 2 at home, maybe more.. Then I take all cars of London probably the same or more as the population have about 6 windows each So the formula would be: time_per_window * ( population * ( 2 at home + 2 at work + 6 per car))
Twice half the time.
Window cleaner can give this answer; I've no experience of such kind.
It depends on the project goal and how you're going to define success. How big is the team? Are they experienced with the work and equipment (high-rise window cleaning will be involved). This could easily become an endless task as windows become dirty again, without a clear objective to say "this is the end" how do you know when you're complete?
If that includes Windows Vista it doesn't seem worthwhile.
Lets just estimate how many windows there are in London,Y, and then work out how long it takes to clean one window,X. Crudely speaking your answer is Y times X. Of course some windows are larger than others and some windows are less accessible than others so these variables would have to be worked into the equation. and by the way I don't work on Sundays, and when I die I suggest you arrange somebody to take over from me.
1 window takes 10 min to be cleaned by 1 Cleaner then the result will be 0.167 Manhour
It depends what time of the day it is. I was on holiday at one hotel and we were warned about the window cleaner doing the windows at 2 am in the morning!
It depends how many windows are married and also how rough the neighbourhood is. Are you sure this for IBM and not Everest?
Next time there is a cause for a1 minute silence, ask everyone to spend that minute to clean one window in London. So total will be 1 minute.
How many people in my team?
0. Hire women for that.
This depends on method of cleansing. Are we talking traditional spray and sponge, high pressure hose pipes or large scale pouring of water and soap over the whole of the city? Also "every single window", what is classed as a window as well as are we talking figuratively or literal?
-Population of London say 10million -Say each home has 5 windows on average (larger houses will have more, flats will have less) -2.5 people per home So the houses of London have 10m*5/2.5 = 20m windows -Say 70% of London is at work -Estimate about a window at work per 10 employees So workplaces of London have 10m*0.7/10 = 700k Say 21m windows, a skilled cleaner could probably do 5 minutes per window, so roughly 102million minutes, or 1.7million man hours.
First I need more data: 1. How many windows are in London - get data from a designated place (the office that permits construction) 2. Take into account that some of these windows won't be there anymore/yet (say 10% - but find better data about that probability) 3. Make an algorithm that sorts windows via sizes (homes vs. offices) and difficulty level (skyscrapers) 4. Run few iterations with different time spend for each window, and finally get the average. 5. Show data about home and office windows separately (as they vary by size and time spent) and show overall average. I'm not a magician, can't calculate it without data 🦸🏻♀️
This question came up in the set venn diagram test. Out of 120 students, those with ID's that are even numbers are doing Physics, and all with ID's divisible by 5 are doing Chemistry, and all with ID's divisible by 7 are doing Maths. How many are doing Physics AND Maths? How many are doing Maths and Chemistry? How many are doing neither subject? etc..6 Answers
Assuming the ID's range from 1-120: Number of students taking Physics: 60 (there are 60 numbers between 1-120 that are divisible by 2) Chemistry: 24 (only 24 numbers between 1-120 that are divisible by 5) Maths: 17 Physics and Chemistry: 12 Physics and Maths: 8 Chemistry and Maths: 2 All three subjects: 1
I got all the same expect Chemistry and Maths where i got the answer as 3. Could you please explain your working? Thanks
I got the same & also 3 (not 2)
This last method is simpler, thanks
How you did that??? I'm so confused with all these maths. Any help???
Why are you single?3 Answers
I'm afraid that's none of your business.
Hi there. Thanks for the review. May I ask you to give me the verbatim questions you were asked, please? Especially the personal ones that you didn't mention? Moreover, how hard were the tests and were they any numerical ones?
Sorry - is this a dating agency? I thought I was here for a job interview. My mistake...
The wifi doesn't work properly. And for every basic test I could think of, they answered that it proved all was fine but still it didn't work.3 Answers
At the end I said there are more important matters than a broken access point, I would just change it, with a different model and everybody could focus on their real job instead of wasting time (Don't answer that, they wanted someone as talented as themselves to manage their LAN)
To be fair to the company, in this scenario it doesn't sound very much like the role was for you. I would totally expect a 'Senior IT Technician/Manager' to troubleshoot basic network problems and resolve them without swapping the hardware. Perhaps working in a technical networked environment is outside your current skillset.
Nick, were you there to know what were my answers? It seems so, according to your certainty. I think my answers did troubleshoot basic network problems, as you said. But they wanted a specialist. In such roles, reliably and cost go above pride. You learn to put efficiency above time consuming pride when you are in charge of the whole IT. I installed hundreds of wifi AP in my careers, the answers I gave Yoti always were enough to provide really good service. At the end I said if I can't find, there's no point in wasting more time, Yoti is not a wifi provider and has more important tasks. Money matters, this role would include budget management. When I installed a wifi service for small companies, it worked for years. The next time I'll install one, I would learn for the latest standards: so much changes in 2 years. No need to be a wifi specialist for a small company, and it's easy to re-learn it when it becomes necessary, with updated literature. For your information, their solution was awful, I would never use it unless I'm bored at work and need time consuming tasks, which never exists when alone for the IT Administration of 170 colleagues. But if they like spending time on settings again and again, it's their business.
take this pen and write the code in BASH to read a CSV file, take the 3rd column and print it in uppercases3 Answers
I didn't know by heart the functions for reading CSV files and uppercase. I said in Systems Administration, we don't write code everyday, our code works for months, even years. And it's not secure to write a script from scratch, since we can't think about everything before going back to the IT Support. I usually take a good script from the internet, read all of it, adapt what needs be.
'I usually take a good script from the internet' does not sound like something somebody experienced in a command language would say. This exercise is extremely basic, one I would expect to find within the first few pages of a tutorial on learning bash with zero experience needed. Perhaps you should not put a command language on your CV if you are not confident in its most basic applications.
You have totally the same spirit as them. Great. Never said they were wrong. I'm pretty sure of my skill with those language as my programs were always reliable and secure and even taught them for a few years at university. I simply dont need them on a daily basis when in charge for the IT. I'd remember more easily how to secure an OS for a job interview.
Do you have a passion for IT?2 Answers
I answered it with the general point that I have grown up around computers and the use of them is second nature to me, as I assume it is with most of my generation. I mentioned that I enjoy puzzles and problem solving, and the world of computing is riddled with problems waiting to be solved.
Were the Maths and English tests you had to complete like psychometric tests?

Where in the periodic table, would you find elements with the largest atoms?2 Answers
This question caught me out as I didn't expect this as I haven't studied Chemistry for more than six years since GCSE level.
I would agree for an IT job.... But as a chemist, yes. Bottom left corner. As expected, atoms become larger as you go down due to extra protons, neutrons, and electrons. However, many non-chemists do not realize that the atoms actually get smaller as you move across the row.
Do you have experience writing Policies?2 Answers
This would be a C level/senior management level task - so no, I didn't just forget to add that level position to my CV.
I have considerable experience not only at IBM but working with JDE clients including Councils and pharma both UK and abroad
