contracts specialist interview questions shared by candidates
Imagine you are working as a programmer for a company called Silver Bars Marketplace and you have just received a new requirement. In it we would like to display to our users how much demand for silver bars there is on the market. To do this we would like to have a 'Live Order Board', that could provide us with the following functionality: Register an order. Order must contain these fields: user id order quantity (e.g.: 3.5 kg) price per kg (e.g.: £303) order type: BUY or SELL Cancel a registered order - this will remove the order from 'Live Order Board' Get summary information of live orders (see explanation below) Imagine we have received the following orders: a) SELL: 3.5 kg for £306 [user1] b) SELL: 1.2 kg for £310 [user2] c) SELL: 1.5 kg for £307 [user3] d) SELL: 2.0 kg for £306 [user4] Our ‘Live Order Board’ should provide us the following summary information: 5.5 kg for £306 // order a) + order d) 1.5 kg for £307 // order c) 1.2 kg for £310 // order b) The first thing to note here is that orders for the same price should be merged together (even when they are from different users). In this case it can be seen that order a) and d) were for the same amount (£306) and this is why only their sum (5.5 kg) is displayed (for £306) and not the individual orders (3.5 kg and 2.0 kg). The last thing to note is that for SELL orders the orders with lowest prices are displayed first. Opposite is true for the BUY orders.
I coded for 2 hours nice clean code well tested. BDD and TDD style, refactored. But they never gave me any sort of feedback.
The very same thing - spent good 2-3 hours on this and nobody bothered to reply. Very unprofessional.
Describe a time when you had to implement a change? How do you maintain accuracy? Which seemed an odd question from someone that relied on a lot of guess work. Compared to other interviews, the interviewing was poor, like they had little interviewing experience. One slouched and had poor listening skills or just wasn't awake. Compared to other organisations I've worked in, I was surprised these two held such important roles.
