Sample iOS & Objective-C Test Question
Consider the following method:
What needs to be modified in order to correctly manage memory when compiled with ARC?
(No special knowledge of Core Text is required to answer this question correctly; you need only consider Core Foundation naming conventions.)
1. Line 2 should be replaced with:
2. Line 2 should be replaced with:
3. Line 4 should be followed by:
4. Line 4 should be removed.
And line 1 should be replaced with:
The correct answer is 1.
1. Does every candidate have to answer the same questions?
Yes. Objective-C & iOS test consists of the same questions for every candidate.
In order to properly compare candidates, they need to answer questions of the same difficulty level, and different questions always mean different difficulty levels.
However, the order of questions and answers is randomized for each applicant.
2. How should I interpret the exam scores?
First of all, you need to keep in mind one very important thing:
The purpose of this Objective-C & iOS online test is not to help you find the best developers.
Its purpose is to help you avoid the worst ones.
For example, you have 5 candidates who get scores of 35, 45, 60, 65, and 80, based on a maximum possible score of 100.
We would recommend you invite the last three (those scoring 60, 65, and 80) to a live interview, not just the one who scored an 80/100.
3. Coding Test vs. Quiz
The test is presented in a multiple-choice, or quiz, format, rather than requiring test takers to write code.
If we used a coding test instead, we would have to check all answers manually, which would obviously be impossible.
4. What skill level is the test for?
The test is primarily created for mid-level developers.
5. What about junior and senior level developers?
The test can also be used to test junior programmers, but you should reduce your acceptance score drastically to compensate.
Likewise, you can use it to test senior iOS developers as well, with an increased acceptance score.
Some will argue that it's pointless to judge senior developers based on a test meant for mid-level developers. This is generally true if you're looking for specific skills in a candidate rather than a broad base of expertise.
But at the same time, anyone can claim to be a senior developer on their resume. If you're concerned that candidates might be overstating their knowledge and accomplishments, this Objective-C & iOS skills test is a good way to determine which ones can actually deliver what they promise.
