Preparing for Technical Questions

To excel in the technical portions of your Tesla interview, focus on the following areas:

1. Coding Exercises

Practice implementing common algorithms and data structures. Be prepared to write clean, efficient code on a whiteboard or in a shared coding environment. Here’s an example of a typical coding question you might encounter:

// Problem: Implement a function to reverse a linked list

// Definition for singly-linked list node
struct ListNode {
    int val;
    ListNode *next;
    ListNode(int x) : val(x), next(NULL) {}
};

class Solution {
public:
    ListNode* reverseList(ListNode* head) {
        ListNode* prev = NULL;
        ListNode* curr = head;
        ListNode* next = NULL;
        
        while (curr != NULL) {
            next = curr->next;
            curr->next = prev;
            prev = curr;
            curr = next;
        }
        
        return prev;
    }
};
