I attended 3 rounds of interview :- Round 1 :- 2 hakcerrank questions. First question was very easy and 2nd was of average difficulty. Round 2 :- Coderpad test :- Given an array of non-negative numbers & a target value, return the length of smallest subarray whose sum is greater than the target value. You need to give running solution with reduced complexity. Round 3 :- Telphonic Interview :- Question 1 :- Count ways to reach the n’th stair Question 2 :- 5 cards magic trick. You need to find out 5th Card Just Google above question and you can easily find out solution. For question 2, I need to explain him the whole trick. We had 1 hr discussion for both the questions. I solved question 1 completely and gave him approx solution for question 2. After few days, I got rejection mail. Don't know what exactly happened.
