New Grad Interview Help — AI for Entry-Level Coding & Behavioral

1. DS&A coding (the main event)

Arrays/strings, hash maps, two-pointer, recursion, trees, and basic graphs/DP — usually easy-to-medium. The AI returns the optimal approach with Big-O so you can explain your reasoning, which matters as much as the answer at the new-grad level. See coding interview help and 15 LeetCode patterns.

2. CS fundamentals

Big-O, basic data-structure trade-offs, OOP, and occasionally OS/networking basics. The AI gives the precise definition so a fundamentals question doesn't trip you up.

3. Behavioral with limited experience

"Tell me about a project," "a time you worked on a team," "how you handled a setback." Use coursework, internships, hackathons, and personal projects. The AI structures your project stories in STAR shape and reminds you to quantify impact even on student work. See behavioral interview help.

1. "Reverse a string" / "Is this a palindrome?"

A warm-up to check you can code and talk at once. Use two pointers from both ends, or a simple loop. State the O(n) time and O(1) extra space so you show you think about complexity even on easy problems.

2. "Two-sum" (given an array, find two numbers that add to a target)

The canonical hash-map question. Brute force is O(n²) with nested loops; the optimal stores each value's complement in a hash map for a single O(n) pass. Say both out loud and explain why you chose the map.

3. "What's the Big-O of this code?"

A fundamentals check. Count nested loops, recursion depth, and the cost of data-structure operations, then give the tightest bound. Know the common ones cold: hash-map lookup O(1), binary search O(log n), a single sort O(n log n).

4. "Explain encapsulation, inheritance, and polymorphism"

The standard OOP trio. Encapsulation bundles data with the methods that act on it and hides internals; inheritance lets a class reuse and extend another; polymorphism lets one interface work across types (a base-class reference calling an overridden method). One crisp sentence and a tiny example each is plenty.

5. "Walk me through a project you built"

Pick a real class, hackathon, or internship project. Cover the problem, your specific contribution, the stack, and one hard decision or bug you worked through. Quantify the result where you can — "cut build time 40%", "handled 500 test users."

6. "Why this company?" / "How do you handle deadlines?"

Light behavioral. For "why this company", give specific, researched reasons tied to your goals. For deadlines, describe how you scope, prioritize, and communicate early when something is at risk — structure even a student example in STAR shape.

7. A light system-design or estimation question

Entry-level versions stay gentle: "how would you design a URL shortener?" or "estimate how much storage a photo app needs." Lay out the obvious components and basic data flow, ask clarifying questions, and reason out loud — nobody expects a senior-level design.
