Montrez que vous êtes au fait des dernières nouvelles des marchés boursiers et exprimez-vous avec assurance et conviction.

Questions d'entretien d'embauche fréquentes pour un trader (H/F) et comment y répondre

Question 1

Question 1 : Parlez-moi d’une action que vous vendriez ou achèteriez maintenant.

How to answer
Comment répondre : Voici l’occasion de mettre en avant vos compétences de vendeur et de vous montrer convaincant. Choisissez une entreprise que vous connaissez bien et soyez prêt à répondre à des questions complémentaires. Argumentez votre réponse sans hésitation.
Question 2

Question 2 : Quelle est la décision la plus risquée que vous ayez prise ?

How to answer
Comment répondre : Si la prise de risque fait partie intrinsèque du métier de trader, cette question vous permet aussi de montrer que vous évaluez les risques de manière réfléchie et bien informée. Expliquez votre cheminement, pourquoi prendre ce risque vous a paru opportun et quel a été le résultat. Cette question vise également à évaluer l’assurance avec laquelle vous justifiez vos décisions.
Question 3

Question 3 : Parlez-moi d’un événement qui s’est produit récemment sur les marchés financiers et dites ce que vous en pensez.

How to answer
Comment répondre : Cette question a un double objectif. D’une part, montrer votre réel intérêt dans les marchés financiers et votre capacité à rester informé dans un contexte qui change quotidiennement (lisez pour cela régulièrement les sites/journaux financiers réputés). D’autre part, exprimer votre point de vue personnel, et tenter de vous démarquer des autres candidats.

There are two racks, X and Y. X contains red (R) socks with probability 0.4 and black (B) socks with probability 0.6. Y contains R with probability 0.7 and B with probability 0.3. I pick a rack randomly. From that rack, I pick 2R. What is the probability that those 2R come from rack X?

First round was a brainteaser/statistics/probability round. First question: you have two fair dice, the sum of which is equal to the value of a security. You have a call option on this security with a strike price of 7. If you are two roll each die once to give you the security value, what are you willing to pay for this call option? Second Question: You have two coins, one fair coin and one with heads on both sides. You randomly choose one of the coins and flip it twice. The results are heads and heads. What is the probability that the coin you flipped is a fair coin. Third Question: You have a spherical balloon that is deflating at a rate such that the radius is decreasing at a constant rate of 4cm/min. At what rate is the balloon deflating when the radius is .25cm. Fourth Question: You have a circle with a radius of one. What is the probability that two randomly chosen points connected by a chord have a length greater than 1? Second Round was all fit. Seems like a pretty unique firm in terms of culture (ski trips, paintball, golf, etc.). The first two guys I interviewed with seemed pretty cool, but the guy from the third round seemed like a hardo. Third Round: They ask you to spend 10 hours reading Hull's textbook on options and futures, which is just about enough time to learn the very basics of options and futures if you have no background. I interviewed with a French guy with a very heavy accent, making it real difficult to comprehend anything coming out of his mouth. First Question: You have a revolver with six chamber slots, and you load two bullets next to each other. You fire the gun once and it's not the bullet. You have the option to either re-spin the chamber, or fire again. Which gives you the higher probability. Second Question: Call option at the money with strike of 100. What is a rough value for the price of the this option. What is the delta of this option?
