Systango Junior Software Developer interview questions

It was a close campus drive for 2017 batch students. There were 4 processes. First one was coding test then 2 technical interviews and last one is HR conversation(if you clear all test and interviews then your salary and joining is discussed). Coding test consists of concepts like array string algorithms etc you can opt for whatever programming language you prefer. First interview is simple only basics of all subjects are asked sometimes programs of average difficulty are also asked and some typical sql queries and latest concepts like machine learning are also asked. I didn't like second interview. It was confusing whether it was a technical interview or a logical reasoning interview. Weird questions were asked like how many cuts required to cut a cake into 8 pieces, why manhole cover is round in shape, how airplane flies etc nothing technical. Since i was not prepared for it I ruined my interview and didn't make it to HR conversation. They said they will call if I get selected but seeing my interview I am completely hopeless. Another guy who was with me also got interviewed in second technical round but his interviewer asked him about technical stuff. I thought my luck was not with me that day. So the interview completely depend on the interviewer and his mood and also your luck.
