I applied through college or university. I interviewed at Susquehanna International Group
Interview
1st round phone interview: 4 math questions asked by one of senior traders.
2nd round phone interview: 2 math questions asked by head of campus recruiter. Stuck on the second math question and failed to go further.
Interview questions [1]
Question 1
I have 20% chance to have cavity gene. If I do have the gene, there is 51% chance that I will have at least one cavity over 1 year. If I don’t have the gene, there is 19% chance that I will have at least one cavity over 1 year. Given that I have a cavity in 6 months, what’s the probability that I have at least a cavity over 1 year?
I applied through a recruiter. I interviewed at Susquehanna International Group
Interview
Recruiter is terrible and rude. Can't discuss any details benefits about the job. It "is not a trading role" but apparently your pay is entirely dependent on your performance and you need trading experience even though it is apparently an operations role. Also if you're going to be disrespectful say that you've got better candidates with more experience applying then why bother wasting everyones time and reaching out.
I applied online. The process took 3 weeks. I interviewed at Susquehanna International Group in Sep 2018
Interview
It was very standard with online assessment then a phone call. Im sure there were other rounds but I didnt pass the first phone interview. 3 Questions for the first phone call. Two probability and one brainteaser. For probability just review Bayes and know how to do linear equations.

Question 1
If you have 4 people who need to cross the bridge at night. They take 1, 2, 5, 10 minutes respectively and 2 can cross at one time. The time it takes 2 people to cross it is the slower of the 2 people. Suppose there is only 1 flashlight which needs be used anytime someone crosses the bridge, how long will it take to cross the bridge.
I applied online. The process took 4 weeks. I interviewed at Susquehanna International Group (Dublin, Dublin) in Jan 2017
Interview
Two rounds of phone interviews, the first lasting 45 minutes, the second one hour.
Interviews began with a couple of behavioural/motivational questions and then moved to small quantitative problems. The questions are very similar to the ones you can find on Glassdoor. Be sure you know bayes formula and are comfortable with clearly explaining solutions on the phone.
Interviewers were very nice and helpful. Unfortunately didn't make to final round even if answered to all the quantitative questions.

Question 1
Usual bayes/probability questions. No mental math.
