list out oops concepts explain polymorphism with real life example? Code for min number of notes(100,500.1000) for given amount (ATM) with atleast 1 100 rs note? explain your project and your contribution in it? why you want to be in Oracle (esp asked to non CS candidates)
In quant mainly from time and distance,profit-loss,pipes,work and time and for verbal basic grammer,tech apti was difficult questions from trees,avl trees,b tree,m ary tree etc.
Got selected for Technical interview.Simple questions on OOPS concepts like 1)what is polymorphism? 2)write the code for bubble sort 3)write the code for binary search and questions on my intern project
The round started with an introduction of both myself and the interviewer. I was asked just one coding question in this round, I had to write a full working code on a shared coderPad. The question was given an arithmetic expression like 4+(5*2)/3-1, I had to determine whether the given arithmetic expression is valid or not. https://codereview.stackexchange.com/questions/181606/determine-if-simple-arithmetic-expression-is-valid/181657 I told him a stack-based approach he was satisfied, then he asked me to do it without using stack, I was able to code that too. Then for each of my approach, he gave 18-20 test cases to pass which were having different errors like unbalanced parenthesis or consecutive operands together ( 4++2) both of my approaches passed all the test cases Finally, he gave me 2 test cases that contained space like (4 2).. my stack solution gave the wrong answer for this I was going to rectify the solution but due to the paucity of time, he said its alright. I was selected for the next round.
