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

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)) Less

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

### Load a file using Pig which has a custom field delimiter and line terminator

You need to write a UDF for Load extending the class LoadFunc

Short Term goals:bug discovery,bug prevention Long Term goals:quality,risk management,customer satisfaction Less

### Why are manhole covers round?

A round cover won't fall into a round hole.

Harder to fall in the hole itself. Vs a square or rectangle cover

Hard to put a round cover on the wrong way. Only 1 way to put it on, even if upside down Less

### a family have 2 kids. if you have seen 1 girl , what is the proberbl the other kids is a boy

chainsaw is right - the question is subtle. Outcome space is (b1,b2), (b1,g2), (g1,b2) and (g1,g2). Now - if you HAVE SEEN the girl (specific girl let's say girl 1) that removes outcomes (b1,b2)&amp;(b1,g2) leaving us with p=1/2 of choice between outcomes (g1,b2) and (g1,g2). If you KNOW (was told) that one is a girl, but do not know which one, than only (b1,b2) is removed from outcome space and the chance is 2/3. Less

answer is 1/2 - the question is very subtle...

isnt it 1/2? BG (boy and girl) and GB (girl and boy) are the same. order is not important. or am i missing something? Less

### Case study round with 30 minutes time is a bit of a challenge.

when was your AMCAT test conducted ??

Guys! If I tell you my identity then what's the point of anonymity!

Hey.. Actually the purpose of asking about the date was when could I expect the interview call as I have already cleared AMCAT exam.So that info could be helpful. Less

### Are you ready to stand the work pressure ?

I missed work pressure.

Yes

Any other questions. Only pressure

### 1 million card applications. \$1 per application cost to do employment verification. 96% pass verification and get a card. 4% fail and do not get cards. Given average profits on cardholders in good standing, and average losses on accounts that default, find the % of denied cardholders that would have to default in order to justify the \$1 per application verification cost .

Anymore info given? I think you'd either need to know the percentage of cardholders in good standing, or the percentage of cardholders in bad standing. Less

This appears to be a trick question that makes you think they want to know the break-even point. However: how can someone default on a credit card that they were "denied" and never issued? Less

### Hoeveel katten zijn er in Nederland?

Waarom vraag je dit? Wil je het aantal katers en poezen weten? Wil je weten welke katten als huisdier geregistreerd zijn? Of wil je weten hoeveel katten in een asiel verblijven? Wil je ook het aantal wilde, loslopende katten weten? Less

Te weinig

Analytisch en stapsgewijs denken. en vanuit een framework proberen te denken

### Are you willing to work 80 hours a week?

I just got hired there as a bra, easily willing to work the 80 hours. Never saw a company that treats you with so much respect and trust right out of the gate. Also spend a lot of money per employee in technology which most people don't know and don't care about. I know and appreciate it as even if a company has the money, most won't spend it. Deloitte realizes their people are their biggest asset. Less

It depends on a person to person - if a resource is efficient and having skill to automate, the 16 hour work for a normal resource can be done in less than 8 hours ! Less

No, I am not interested in working for a company that doesn't value life/work balance. Thank you for your time and good day. Less
