Landbay Software Developer interview questions

I prepared for an interview call which was through the agent. Had to learn so many things regarding their company what they do and about their peer to peer lending strategy and about their competitors as the agent advised that many people got rejected because they didn’t know much about the company. It feels like Landbay has billions of revenue and they would like any future candidate to know everything about them. The phone call was with HR and asked about the company’s history, awards, peer to peer strategy etc. Second part was with someone who mentioned is number 13 in the company in terms of hierarchy. It was all about java questions what docker is and asked me to describe microservices. I did explain what docker is and what’s microservices in detail. His last question was what is Hasmap and I went through explaining what is it and all the Following are few key points to note about HashMaps in Java - A HashMap cannot contain duplicate keys. Java HashMap allows null values and the null key. HashMap is an unordered collection. It does not guarantee any specific order of the elements. Java HashMap is not thread-safe. You must explicitly synchronize concurrent modifications to the HashMap. However feedback was bad mentioning that I misunderstood the question for Hasmaps. I analysed docker and microservices fine. I am not sure why he didn’t make clear the question about hashmaps. Such a waste of time talking and learning about them. Really unexpected the outcome. I thought at lease they are going to send me their test.
