Re: Optiver TestOnly bother going if you are gifted with numbers. Not good, or very good; exceptional.
I thought I was very good at mental arithmetic, and so did the other 47 out of 50 people (>90% oxbridge/imperial) who got sent home after round one.
Best of luck! -

Did you make it through? My understanding is that the maths is ok. Anyone can answer the questions when given enough time. However i hear that here you just have approx 10 secs per question??(Original post by Slumpy)
I thought it was pretty easy tbh, and I'm not that great at mental arithmetic.
Edit-that might be a bit false actually. I am pretty good at arithmetic, but I know people who're better.

Thanks for the link. Looks like i will have to brush up on my simplifying. Did you manage to get the job? If so, whats it like? Otherwise, during this process, how did you find optiver? Tnx(Original post by Slumpy)

Re: Optiver TestNah, I didn't do much prep for the next rounds. I think your odds aren't too bad past the numerical rounds. They seemed pretty nice during the process, though I did get the impression that they're (unsurprisingly) pretty ruthless with people being unprofitable traders.(Original post by PrincePauper)

Re: Optiver TestThis reminds me of Tibra Capital. They have a similar style math test...(Original post by salmon1)

Re: Optiver TestDid it in Feb/March
From what i remember...about 30 people....1 person passed easily (she answered all 80 and only got 3-4 wrong) and 1 was in the grey zone. Most people were from LSE from what i remember seeing on the register.
I answered 73 out of 80 being pretty confident that i didnt get that many wrong, however I was unaware that it was negatively marked by -2 (every wrong / missed answer = -2 on your score, whereas I thought it was -1 so took some chances).
Does seem like a ruthless corp to be honest...could just tell from the organisers attitude...friendly but wouldnt hesitate to stab you and twist.
I think it works out to be 6 seconds per question -

Re: Optiver TestI was nosing on their website and noticed this question (you have to solve it and send the answer with your application for the Data Analyst / Junior Researcher role). Interesting one, didn't take long but I'm not particularly confident with my answer! Are their question shorter versions of things like this? Don't know why I'm asking, no intention of applying lol. tt1306980

Can you solve this puzzle ?
There are 100 girls and 100 guys. The girls each have their individual preference list for which guy they’d like to marry. Each list contains all 100 guys in the order of the girl’s preference. We’d like to match them up as well as we can according to their preferences. To measure how well we’re doing, we assign each match a number: the number of the guy on the girl’s preference list. So if a girl gets to marry her 2nd choice, for example, we assign the number two. We’d like to keep the sum of numbers for all the matches as small as possible. What is the number we’ll get in the WORST case? -

Re: Optiver TestTibra is formed out of ex-Optiver.(Original post by fail@maths)
This reminds me of Tibra Capital. They have a similar style math test...
And there's now a third firm which has popped up made of ex-Tibra and ex-Optiver. -

1. 3/153 as a decimal
2. 1/8 * 560
3. 0.625 / 150
Etc... cba to create more examples but i'm just trying to illustrate that the questions are not hard, although they do get slightly harder than the above... You have 80 to do in 8 minutes, so that's one every 10 sec. You score 1 point for every correct answer, and you receive -2 points for every wrong or skipped answer. E.g. you get Qs 1 and 3 correct but skip question 2 = 0 points overall. You are normally required to score 55+ to advance to round 2.
You should be very comfortable with fractions and decimals and converting one to the other (quickly), and with general arithmetic. A maths/engineering degree will get you nowhere here... -

Re: Optiver TestDamn, congrats to anyone that passes that test. 80 in 80 minutes? Christ they're all right if you can write them out but doing them every 10 seconds in your head is crazy.(Original post by salmon1)

I used to think I was good at mental arithmetic. I stand corrected

Re: Optiver TestI don't like your odds of passing with that maths(Original post by salmon1)

Pass mark is only like 54, though it is negatively marked.(Original post by M1011)

Re: Optiver Test"only"(Original post by Slumpy)
Pass mark is only like 54, though it is negatively marked.
I fail to see how someone works out 0.625/150 in their head in 6 seconds. Or if we assume 100% accuracy and a pass mark of 54, under 9 seconds. Then to repeat that speed constantly 50+ times in a row, yikes. -

Re: Optiver TestObviously (5/8)/150=1/240, then guess from there (it's multiple choice). That's what, a second or two? The only tough bit is keeping concentration up.(Original post by M1011)

Re: Optiver TestYea it makes sense when you put it like that, but making that first choice to swap it into 5/8ths etc within those tough time limits = very challenging.(Original post by Slumpy)

Can you apply your outrageous maths skills to the question I quoted a few posts above? Interested to know if I got it right or was completely off base. My answer is at the end of my comment (google), didn't want to make a spoiler.
