Samsung SDS Software Developer interview questions

Feeling really uncomfortable in the video call interview with a senior software engineer at this company based in Singapore. And the big boss was also in the call and speaking less (eating watermelon and watching the show?) The senior software engineer, an interviewer was speaking loud & impolite and can't pronounce some words correctly, especially the word: VERSION. I was so sorry that my listening wasn't so good and my englik also no good. I just heard that he had repetitively speaking "VAASION" on his technical questions but I can't understand what 7 he was saying at that moment. No choice, I had to request him to repeat his sentence again and again. At the end, I still didn't get it. Sorry about that..
