RenewBuy Python Developer interview questions

I have interviewed here 3 times but for some reason never got hired. I always had a hope that they might consider me seeing my dedication that I apply again and again and I would love to work with them. I interviewed first time during my college days and it didn't go well because I didn't have the required knowledge, so the interviewer told me to come back after a year. I tried again next year for switching from my current job as I liked this company for some reason but didn't clear. Third and last time I cleared till 2nd last round after which there was an HR round to discuss salary. But I guess they went for a fresher as he might have asked for a lesser salary (I'm assuming this because my turn for HR round was after that guy and as soon as he was done with his round, they announced everyone to leave one by one.). I think that guy accepted an offer somewhere else because I again got to see a vacancy for the same post again in a month or so. After this I never looked back at this company. Not sure what were they looking for.
