Just finished a Intuit OA , the overall feeling is moderately difficult, but very much examines coding skills and code robustness. Although there are not many questions, you have to be careful with boundaries, type judgment and logical coverage in every question. On my side, both questions went well in AC, and I'd like to share my thoughts on the topic while it's still hot.
Application Process Review
Intuit's hiring process is very standardized:
- delivery channelThe following is a list of some of the most popular products and services in the world: You can submit your application via the official website or LinkedIn, and you will usually receive an OA invitation within a week.
- Evaluation PlatformThe test was conducted on HackerRank and was limited to 90 minutes.
- Title structure: 2 programming questions of medium difficulty, focusing on coding details and string handling;
- Follow-up process: Candidates with excellent OA performance usually receive a follow-up email from the recruiter within 3-5 days to schedule a VO.
OA Topic Details
Q1: Find the Common Word from Three Strings
Problem.
You are given three strings of equal length. For each index I, find the common letter that appears in all three strings at position I.
- If no such letter exists, print
"No solution". - If multiple positions have multiple valid letters, print
"Ambiguous". - Otherwise, print the unique valid word.
Ideas and realization points:
- Iterate over all character positions and take the intersection of the three;
- If a bit intersection is empty → no solution;
- If more than one optional character exists → Multi-solution;
- Otherwise spell out the only answer.
This is a logically simple but fault-tolerant question that requires string boundaries, repeated letters, and case sensitivity to be considered in advance.
Q2: Palindromic Tree (Eertree)
Problem.
Implement a palindromic automaton to count all distinct palindromic substrings in a string.
The automaton maintains suffix links to track the longest palindromic suffix dynamically.
At the end. total_nodes - 2 equals the count of unique palindromic substrings.
Thoughts and Points:
- Create two virtual root nodes:
-1(odd root) vs.0(even root). - Each time a new character is inserted, backtrack from the current longest palindrome suffix to find an expandable node;
- If the new echo does not appear, create the node and update the suffix link;
- After the traversal is complete, the total number of nodes minus 2 is the answer.
This question focuses on whether you understand String structure + Dynamic extension mechanism + Reply center maintenance. Well-written code is usually logical and space efficient.
Frequently Asked Questions FAQ
Q1：What is Intuit's OA difficulty level among large manufacturers?
A: Overall moderate. No complex algorithms, but implementation details are more delicate than the average OA, especially the second question requires stable logic, suitable for people with solid code skills.
Q2: Can I use Python?
A: No problem at all. The HackerRank platform supports multiple languages, but we recommend Python or C++ for more efficient debugging.
Q3: How long does it take to get an interview invitation after OA?
A: Usually within 3-5 business days, if the OA performs well, the recruiter will ask the VO directly.
Q4: How exactly does Programhelp's assist work?
A: We provide Remote Voice Reminder + Idea Guide service, which is whole process without any trace and will not disturb the answering environment. The system will remind you to optimize the direction by voice when you have a stuck point or logic confusion, to ensure that you finish steadily within the rhythm.
Final chat.
Intuit's questions are more like "Are you a person who can write logic on your own".
It's not about brushing up on problems, it's about subtlety + consistency + debugging ability.
That's the key to Programhelp's breakthroughs for our trainees -- precise assistance at key points to ensure that the logic closes the loop.
If you've also recently been preparing Intuit / Amazon / Stripe / Databricks This type of company, OA.
Don't take it hard by yourself.
Come and try our Remote unmarked assists, so that you, like this trainee, have a steady AC and don't get flustered.
