I was contacted by an HR consultant from an intermediate company and proposed me the job role, the job offer caught my attention it'is interesting, then bitFlyer has sent the quiz, I was disappointed because I figured out the problem and applied the Knapsack algorithm, despite that I'm sure that the algorithm was correct because I've found exactly the answer mentioned in the example of the Hint section. But they said that I must find a gamma value for alpha transactions, so I found that value as expected by the algorithm! I'm wondering why they rejected my application? when I was more curious I asked them why? what you expected me to do? they didn't answer.... I was disappointed
