Not any flaws in the interview process. But some interviewers in this company are illogical. In fact, the interviewer needs logical understanding about some concepts, here when the interviewer asked me question Que. Write test cases on functionality which gives an output triangle if we provide 3 points? My Ans. If we put 3 points which makes the collinear vector then output should not be triangle or software will display an error message... The interviewer suddenly stopped me and utter this is not test case this is the functionality, further, we can add it in our software...again I wrote 5 to 6 more test cases on same functionality but interviewer declined that... About the interviewer... 1. They want perfect answers to the questions but not the logic. 3. If the interviewer said you write down any answer then while writing an answer you should utter it. 4. Be perfectly prepared for everything you have learned in your life because they will ask anything they want to, no matter it is related to your current profile or not. All the best!
