How many man hours would it take to clean every single window in London?

21 Answers

Thank you for the time, this job's not for me...

If that includes Windows Vista it doesn't seem worthwhile.

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)) Less

An analytical question about: Say you have ten stacks of coins with ten coins in each stack, each coin weighing 1g. However, one of the stacks has 2g coins instead of 1g coins. If you have a weighing scale and can only make one measurement, how do you determine which stack of coins weighs 2g each coin?

6 Answers

It's simple. Take 1 coin from the first stack, 2 coins from the second, 3 from the thirds - you see where this is going - finally 10 from tenth stack. put them on weighing scale. If in result you get 56 - it was first stack, 57 - second.... 65 - tenth stack. Less

1-If all the coins are made from the same material and same diameter, then the heavier coin stack should be slightly taller. 2- Weight all the stacks at once, and remove each stack until you see a dip in the tota weight . Less

I didn't quite understand what you meant. So there are 10 coins, 9 weigh 1 gram, and one weighs 2 grams? The second sentence seems contradictory. If you can only make one measurement, then you would divide the stacks into two. Place each stack on either scale, and whichever one is heavier contains the 2g coin. Less

Tech interview frameworks are pretty simple as they are few in number. For this question I applied the implementation strategy framework which turned out to be right. But please do not jump to a conclusion right away. I had to ask many questions and I eventually managed to whittle down the problem to that of an effective and common data management solution where the interviewer offered me multiple choices and I decided to go with the ERP system. And then she asked me how I would go about installing it in multiple offices across the world and in a given time frame etc....It was pretty straightforward from that. The important takeaway is frameworks are important but do not be bound by them. And they do not look for a right or wrong answer from you, but instead study your thought process and your approach to problems you have no idea about...Hope this helped. Best of luck!! Less

What other frameworks are there in tech interviews?

What framework did you use in this case? I'm pretty new to case interview, and feel the frameworks are mostly about profit or market. How to use them in tech case interview? Thank you!! Less
