I applied to GoIbibo through LinkedIn. The process took about a month. I received a call from the HR regarding the same to schedule an interview. Fast forward to the interview. My interview was taken by a senior software developer who seemed to have a great deal of knowledge. He first started with simple Object Oriented Programming concepts like -What do you mean by Abstraction? -What do you mean by Polymorphism? -Then to take a deeper dig into the questions he tried confusing me between run time and compile time polymorphism. -From run time and compile time polymorphism he mentioned examples of function overloading and overriding and would give confusing statements about both. After a good drill on Object Oriented Programming he went on to ask me questions about my projects like- -What is difference between MongoDB and SQL?(As I had used MongoDB in the project) -Are joins possible in MongoDB? -Why did you use MongoDB? -Does your project work for multiple users logged into the platform at a time?(Drilling me about page sessions) -As my project was based on MVC he then went on to ask the corresponding Model, View and Control layers.He then repeated a few sentences so as to confuse me with the respective layers. -More questions about DAO-Data Access Object. He then gave me a DSA question- Finding loop in linked list We discussed various approaches of solving this problem with and without extra memory spaces. He then asked me if I had any questions for him and I asked him for my feedback for which he explained the second puzzle that I could not answer. The interviewer was extremely friendly but would keep confusing me and contradicting my statements.It was however a good experience interviewing with Ibibo. Hope this post helped. All the best :D
