J'ai postulé en ligne. Le processus a pris 3 semaines. J'ai passé un entretien chez Optiver (Amsterdam) en juil. 2018
Entretien
Four/Five stages: 1)Online application and CV screening 2)Online Mathematics Test 3)HR Telephone Interview 4) Technical Skype Interview with Trading team members 5) Face-to-face interviews
I made it to round 4. HR interview is pretty easy. Just learn your motivations etc. and why you like this company. Interviewer was polite and easy to talk to.
Then I had the Skype Interview. In advance, you are asked to prepare by reading a market making document they provide. In addition you have to read on Option Theory, which they suggest a particular book for. However, nothing on options came up.
I have never had a worse experience in an interview. The Interviewers were incredibly rude. They were always sniggering to each other clearly about me. They made rude comments, such as "By the way this is not rocket science, hurry up." Whenever I told them the connection was breaking down they rolled their eyes. Never have I come across two people with worse manners. This company only looks to employ the smartest people and not those who are polite etc.
The interview was pretty messy too. One of the questions I supposedly fell down on was to calculate the number of petrol stations in my country, which would then be part of the Market Making game. Now I went through a pretty methodical way of calculating this, but I raised my doubts as the number seemed unusually high. I told them this. But on the feedback they raised this as one of the reasons for not passing. I don't see how not having the knowledge required to calculate this question (e.g. no. of cars or something like that) means that I shouldn't be allowed to go through. My method of calculating was fine, just that the number was high.
Then later on in this MM game I was asked to make a confidence interval where I was 50% certain that the true value of a certain number was between this. Thus I calculated a 50% C.I. However, the interviewer meant to say what I think I am 50% sure of the answer being. Again this was another supposed stumbling block to me going through, despite me executing the market making game very well.
Finally there were some mental maths and probability questions. The probability question turned out to be redundant because the Trader didn't know the rules of tennis. Therefore an answer with an infinite amount of possible outcomes was the result, which is naturally not possible to calculate. I told him this, but he seemed to think that I wasn't able to do the question.
I am still yet to have an apology from the Traders, for the way they behaved.
Make sure you understand when to buy and sell in MM.
Questions d'entretien [2]
Question 1
You start a tennis game at 30-30. You have a probability of winning each point of 0.6. What is the probability of you winning the game?
spent about 1.5 months pretty much purely dedicated to preparing for interviews for all the pre-penultimate programs (Optiver, IMC, JS, SIG, Citadel, etc). I used these resources:
Green book (Really good starter but I got bored of it after a few weeks)
EverythingQuant (Went through literally every single interview prep question, went through the interview guides, and completed the probability course just to make sure I covered all bases)
Briefly read through this guide
Watched coding Jesus in my spare time (not sure if this helped directly lmao but he’s a great creator and very informative)
Mental math test, beat the odds, online puzzle like games etc online, brain teasers during physical interview and a behavioral interview where they want to assess how competitive and assertive you are.
OA was weird and hard. there was only three sections (i think) this year compared to 5 last year. questions are weird and I don't know how they can judge your ability base on that.
