Hackerrank Exam Structure and Content 3 — Questions and Answers
Question 1: Approximately how many coding challenges are included in the HackerRank Python (Basic) certification exam?
- 1–2 challenges
- 3–4 challenges (Correct answer)
- 8–10 challenges
- 15–20 challenges
Correct answer: 3–4 challenges
The Python Basic certification typically contains 3–4 coding challenges to be completed within the time limit.
Question 2: What happens to a candidate's score if their code passes only some of the test cases for a problem?
- They receive zero credit for that problem
- They receive full credit regardless
- They receive partial credit proportional to test cases passed (Correct answer)
- The problem is skipped and not counted
Correct answer: They receive partial credit proportional to test cases passed
HackerRank awards partial credit based on the fraction of test cases a solution passes.
Question 3: Which of the following Python topics falls under the 'Functional Programming' domain of the HackerRank Python Basic certification?
- Thread synchronization
- Lambda functions and map/filter (Correct answer)
- Django view functions
- Socket programming
Correct answer: Lambda functions and map/filter
Lambda expressions and built-in higher-order functions like map and filter are assessed under functional programming.
Question 4: In the HackerRank Python (Basic) certification, which data structure topic is most likely to appear?
- Red-black trees
- B+ trees
- Lists, dictionaries, and sets (Correct answer)
- Bloom filters
Correct answer: Lists, dictionaries, and sets
The Basic exam focuses on Python's built-in data structures: lists, dictionaries, sets, and tuples.
Question 5: How long is a HackerRank certification valid after it is earned?
- 3 months
- 6 months
- 1 year
- Indefinitely (no expiration) (Correct answer)
Correct answer: Indefinitely (no expiration)
HackerRank certifications do not expire and remain on a candidate's profile indefinitely.
Question 6: Which of the following describes how HackerRank evaluates Python coding submissions for correctness?
- Manual code review by HackerRank engineers
- Static analysis of code style only
- Automated test case execution against hidden test inputs (Correct answer)
- Peer review by other certified candidates
Correct answer: Automated test case execution against hidden test inputs
Submissions are evaluated automatically by running the code against a set of hidden test cases.
Question 7: What is the significance of the HackerRank Python (Intermediate) certification compared to the Basic level?
- It replaces the Basic certificate once earned
- It tests more advanced topics like decorators, generators, and complex OOP (Correct answer)
- It is exclusively for Python 2.x syntax
- It focuses on web development frameworks like Flask
Correct answer: It tests more advanced topics like decorators, generators, and complex OOP
The Intermediate certification builds on Basic concepts and includes advanced topics such as decorators, generators, and deeper OOP patterns.
