A un Graduate IT Consultant le preguntaron...18 de mayo de 2014

### This question came up in the set venn diagram test. Out of 120 students, those with ID's that are even numbers are doing Physics, and all with ID's divisible by 5 are doing Chemistry, and all with ID's divisible by 7 are doing Maths. How many are doing Physics AND Maths? How many are doing Maths and Chemistry? How many are doing neither subject? etc..

I got the same &amp; also 3 (not 2)

### WHAT IS YOUR AGE??? - A totally prohibited ground in HR context.

5 respuestas

Look at the question: "What is your age?" That's different from "How old are you?" Answer accordingly. Menos

I was asked this question by the CEO of a company during my telephonic interview. Even though I didn't ask, told me his age. That just seemed weird and not very professional. This wasn't Deloitte. Menos

So many ways to find this information - in a, sort of, sneaky way. Has no-one noticed that now you not only being asked for your degrees but what year you obtained them - easy enough to extrapolate in the majority of cases... Menos

### Find the unique value in an array

5 respuestas

Example: while (start Check for equal to target value / \ (1) (3) | | | ----&gt; start = (this leaf index) : if target is &gt; parent | ----&gt; end = (this leaf index) : if target =. Use index 8 and 3 in the array above as two prime examples. Furthermore, it would take a stroke of luck to find the unique value "1" take this for example: You have a struct named MyStruct with members ID which is type int and Value which is type int. If you randomly generated 'n' number of these and all except one were duplicates, how would you find the unique value? Menos

public struct MyStruct : IEquatable, IComparable { // Saved for the sake of not having to recalculate every time its called (Specifically for this example.) private int _hashCode; public MyStruct(int id, int value) { ID = id; Value = value; _hashCode = 0; } public int ID { get; } public int Value { get; } public int CompareTo(MyStruct other) { return GetHashCode() == other.GetHashCode() ? 0 : GetHashCode() (MyStruct a, MyStruct b) { return a.GetHashCode() &gt; b.GetHashCode(); } public static bool operator {Value}"; } public override bool Equals(object obj) { return obj is MyStruct &amp;&amp; obj.GetHashCode() == GetHashCode(); } #endregion } Menos

internal class Program { private static void Main(string[] args) { // Create a unique value var unique = new MyStruct("Unique".GetHashCode(), 0x200); // Prepare for all test cases var executionArray = new Func[] { executeFindCustomStructWithLinq, executeFindUniqueWithHashSet, executeFindUniqueWithBinaryTree }; // Execute test cases and get results var resultsTypeArray = executionArray.Select( method =&gt; new {Name = nameof(method), Result = method(unique)}); // print the results from the case resultsTypeArray.ToList().ForEach(item =&gt; WriteResults(item.Name,unique,item.Result)); Console.ReadKey(); } private static void WriteResults(string methodName, MyStruct orig, MyStruct target) { Console.WriteLine(\$"{methodName}: {orig} == {target}"); } private static IList CreateDataSet(MyStruct unique) { var random = new Random(); var amount = random.Next(0X0, 0x100); var myStructFactory = MyStructFactory.Instance; var dataSet = new List((amount*2) + 1); dataSet.AddRange(myStructFactory.Create(amount)); // create a copy of the base data set var holdingBuffer = new MyStruct[dataSet.Count]; dataSet.CopyTo(holdingBuffer, 0); // Insert Unique somewhere in the set dataSet.Insert(random.Next(0, dataSet.Count), unique); // add duplicated base dataset dataSet.AddRange(holdingBuffer); return dataSet; } #region ExecutionExamples private static MyStruct executeFindUniqueWithBinaryTree(MyStruct unique) { // Keep in mind this would only work if we knew the value before trying to parse the data set. var dataSet = CreateDataSet(unique); var orderedDataSet = dataSet.OrderBy(@struct =&gt; @struct).ToArray(); var start = 0; var identifiedUnique = new MyStruct(); var end = orderedDataSet.Count(); while (start (); var identifiedUnique = new MyStruct(); for (var i = 0; i a ^= b); return identifiedUnique; } #endregion } Menos

### when the CEO tells you "i don't know!" on a strategy question you ask him. How should you respond to that?? :)

3 respuestas

no its just because he cant comprehend anything

This is pure comedy

You might think that he has real world experience that you as a recent graduate don't understand, and your questions are about theory which really don't apply in the real world. That might be why he "didn't understand" your question. Menos

### Is the Salesforce.com/Force.com platform a "relational database"?

5 respuestas

I think it falls under the object-relational umbrella. Sure it does relationships, but it does more than that, and with the abstraction of the API you never really get at the full relational structure of the underlying oracle DB. Menos

Answer number four is good I accidentally marked it as a negative

Yes it is, the platform is built on top of an oracle relational database.
