Works Applications Junior Software Engineer interview questions

1st Round: Coding round where I was given 3 questions. I answered 2 questions completely and 1 question partially. Video round: Asked for sending videos to HR team like why I wanna join, Where I see myself in 5 years. 3rd round: There was a Chinese guy. I have very good experience with chinese people, they are modest. The guy asked me two questions. One was paranthesis matching, 2nd was Two pointer sum in rotated sorted array. 4th round: There was an Indian guy who was very frustrated with life. He was doing company code in between interview (may be missed his targets). He asked me: LRU Cache implementation Count number of words in dictionary using trie. kth smallest element given two sorted lists. I answered all the questions but for 3rd one I gave him a log(n) solution which was not in his template from where he was asking. If you don't have brain why ask the question. I firmly believe that guy rejected me because I am an Indian. He mentioned something like that too.

I applied via LinkedIn. They wanted 1+ years of experience in Software Development. The HR contacted me after almost a month and was extremely nice and professional in her work. The first round was a live coding round in which 2 interviewers were there connected via Skype Video Call and I was asked to share the screen so that they can see me typing the code. They prefer Java as the programming language and Eclipse. There were two questions and an hour but the time was not very stringent. Question 1 : Given two sorted lists return a list with the common elements. Calculate complexity, Edge cases and optimizing for large input scenarios were asked. Question 2 : Given a M x N matrix with 0's and 1's find out the number of islands represented by 1's. Can be found in geeksforgeeks and solution is plain counting number of connected components. The interviewers were very inexperienced but they were really nice and respectful to mute the mic when they were discussing among themselves because they didn't want me to be distracted. Got shortlisted for Round 2 which was a technical background check after almost a week. Round 2 : Same process. Two people were connected to me via Skype video call. I have given a lot of interviews but I felt this was my worst experience so far. The interviewers were extremely unprofessional, inexperienced and disrespectful. They started asking very irrelevant questions that took most of the time. They didn't even ask "Tell me about yourself, work experience etc." They were constantly giggling , talking in Hindi and sarcastically talking about me having no chances even without muting the mic. They only asked from my CV about what I did. No elaborate technical discussions happened. They asked extremely easy questions from geeks for geeks like query in SQL to extract 2nd highest salary. My interview went pretty good however I got rejected in this round without further explanation. It seemed these unprofessional dudes was simply playing the fool just because they were interviewing a candidate 3 years junior to them.
