Fragen im Vorstellungsgespräch: Softwareentwickler

import java.util.HashSet; import java.util.Set; public class One { public static void main(String[] args) { System.out.println(palindromeTest("barbarabar")); } public static int palindromeTest(String string) { Set palindromes = new HashSet(); boolean canBePalindrome; for (int i = 0; i = 0 && i + offset < string.length() && canBePalindrome) { if (string.charAt(i - offset) == string.charAt(i + offset)) { palindromes.add(string.substring(i - offset, i + offset + 1)); offset++; } else { canBePalindrome = false; } } } return palindromes.size(); } } How much time was given for this task?

int solution(String X) { int palCount = 0; int singlePal = X.length(); for (int i = 0; i < X.length(); i++) { String sub = "" + X.charAt(i); boolean isPal = true; for (int j = i + 1; j < X.length(); j++) { sub += X.charAt(j); if (X.charAt(i) == X.charAt(j)) { // check if a palindrome for (int k = 0, l = sub.length() - 1; k < sub.length() / 2; k++, l--) { if (sub.charAt(k) != sub.charAt(l)) { isPal = false; break; } } if (isPal) { palCount++; singlePal -= sub.length(); i = j; } break; } } } return palCount + singlePal; }

Did anyone get asked to do this in JavaScript?

You can get the full application in Dhiraj Patra github repo.

Not gonna lie, your code is pretty bad, no separations of concerns, no contextual logging. The position was for a senior engineer, your stuff is junior level at best. Don't lash people out for your inadequacy of the role.

Sorry but I have to be honest, your code is pretty bad. To me the true is, you are not good enough and that's it. You also were very anti ethical exposing the whole code challenging to your Github

use filter and map

Well its pretty basic. 1. Convert String into character array. 2. Check if Array's length = 48 && intValue <= 57) { int numValue = values[intValue - 48]; finalNumber += (numValue * Math.pow(10, power)); power--; } else { System.out.println("Not a number"); return; } } finalNumber *= multiplier; System.out.println(finalNumber); }

Program ___________________________________________ int[] values = {0,1,2,3,4,5,6,7,8,9}; String test = "-123"; char[] arr = test.toCharArray(); if(arr.length = 48 && intValue <= 57) { int numValue = values[intValue - 48]; finalNumber += (numValue * Math.pow(10, power)); power--; } else { System.out.println("Not a number"); return; } } finalNumber *= multiplier; System.out.println(finalNumber); }

public int minWindow(char[] str, char[] chars, int startIndx, int i, int j) { if (j == chars.length) { // found the solution // check the minimum if ((i - startIndx) 0) { return minWin; } return -1; }

static int minWin = Integer.MAX_VALUE; public static int minWindow(char[] str, char[] chars, int startIndx, int i, int j) { if (j == chars.length) { // found the solution // check the minimum if ((i - startIndx) 0) { return minWin; } return -1; }

Project created

How you created the app? What sort of ui and code organisation you adopted that satisfied mytaxi team ? I did created the app with was functional as per their requirements but certainly that was not what they are looking for please let us know

Did you use unit tests in your code?

They will be testing your interpersonal and motivational skills.

Could you please post the questions that were asked to you and the kind of concepts that were touched upon, as part of the last 3 hour interview round?

round 3 questions: reverse a string recursively. explain architecture of Cassandra (I worked on Cassandra in previous projects) explain consistency configuration in Cassandra.

Did you get offer ? How was second round ?

They did not come back with anything yet, not even an email. But I guess there is no offer.

Ok ,could you tell me more about your second round ,I mean what kind of technical questions they asked ?
