A un Summer Internship - Quantitative Investment Strategies le preguntaron...10 de abril de 2012

### Suppose that you have a fair coin. You start with \$0. You win 1\$ each time you get a head and loose \$1 each time you get tails. Calculate the probability of getting \$2 without getting below \$0 at any time.

1/3

1/3 Because if he requires 2 heads = \$2, then it means he require HH out of {HH,HT ,TH,TT} We cannot consider TT because it would turn to zero. Therefore, he has 1 chance out of 3. Hence 1/3. Menos

Marchov chain with 2 and -1 absorbing OR geometric series 1/4^n from 1 to inf=1/3 Menos

### A glass bottle full of liquid weighs 100 ounces. If you remove half the liquid, the bottle now weighs 60 ounces. How much does the bottle weigh with nothing in it?

5 respuestas

0.5x + y = 60 x + y = 100 y = 20 is the weight of the bottle x is fluid weight Menos

20 Why? Because Replace y with 100 - x Getting 0.5x +100 - x = 60 Then -0.5x = -40 Thus x = 80 80 + y = 100 Menos

x+2y=100 x+y=60 Calculate for X

I had a hard time, but the woman was super nice about it and I realized I had to use algebra to solve the problem. Just be calm under pressure and you'll do fine. Menos

I don't want to be rude but what kind of Algebra did you have to use ? It seems like a high school level equation to be fair Menos

Really? I guess the only catch is if tax is included.

Etude de cas - marketsizing

Imaginons que je n'ai aucun chiffre. Soit je fais de mes connaissances (ami/collègues) un échantillon que j’espère représentatif. En précisant cela à l'examinateur Soit j'admets que donner un tel chiffre sans information complémentaire est contraire à une idée d’honnêteté intellectuelle. Par conséquent, je pose plus de questions sur les données du problème. Quand aux ' il est probable que ' franchement j’éviterai sans démontré surtout un ego surdimensionné. Menos

On sait que selon les estimations, entre 2% et 5% des trajets à Paris se font à vélo, tablons donc sur 3%. Sur ces 3%, il est probable que seul un tiers concerne les trajets domicile-travail (aller ou retour), nous arrivons à 1% des déplacements à Paris. Environ 2millions de personnes travaillent dans Paris, cela nous laisse donc avec 20 000 cyclistes. Si je peux ajouter quelque chose, ce chiffre risque d'augmenter grâce à : 1) l'effet positif d'un exercice physique sur la santé 2) l'effet de l'indemnité kilométrique vélo (facultative mais tout de même) Menos

Vague as possible because I sensed he was conducting interviews only for free consultation purpose. If you conduct an interview, don't feel bad about not getting a single response, just monitor this company's employee list and you will note that the position was never actually being offered. Menos
