Twitter (X) Placement Process (2024-2025)

The process may vary by campus, but typically includes:

1. Online Coding Round (on platforms like HackerRank, Codility, or Mettl):
   • 3-4 coding questions (DSA, algorithms)
   • 60-90 minutes
   • May include MCQs on CS fundamentals, aptitude, and output prediction
2. Technical Interviews (2-3 rounds):
   • Data structures, algorithms, OOP, DBMS, OS, and project discussion
   • Coding on whiteboard or shared doc
   • May include puzzles and system design (for SDE2+)
3. Managerial/Team Fit Round:
   • Problem-solving, design, and behavioral questions
   • Deep dive into projects/internships
   • Scenario-based and situational questions
4. HR/Behavioral Interview:
   • Motivation, teamwork, leadership, company fit
   • Compensation, relocation, and benefits discussion

Sample Coding Questions (Recent Twitter/X Papers)

Easy

1. Find the Missing Number Given an array containing n distinct numbers taken from 0, 1, 2, …, n, find the one that is missing from the array.

def missingNumber(nums):
    n = len(nums)
    return n * (n + 1) // 2 - sum(nums)

2. Valid Anagram

bool isAnagram(string s, string t) {
    if (s.length() != t.length()) return false;
    int count[26] = {0};
    for (char c : s) count[c - 'a']++;
    for (char c : t) count[c - 'a']--;
    for (int i = 0; i < 26; ++i) if (count[i]) return false;
    return true;
}

Medium

1. Group Anagrams

def groupAnagrams(strs):
    d = collections.defaultdict(list)
    for s in strs:
        key = tuple(sorted(s))
        d[key].append(s)
    return list(d.values())

2. Implement a Stack Using Queues

class MyStack {
    queue<int> q;
public:
    void push(int x) {
        q.push(x);
        for (int i = 1; i < q.size(); ++i) {
            q.push(q.front());
            q.pop();
        }
    }
    void pop() { q.pop(); }
    int top() { return q.front(); }
    bool empty() { return q.empty(); }
};

Hard

1. Longest Consecutive Sequence Given an unsorted array of integers, find the length of the longest consecutive elements sequence.

2. Design Twitter (Mini Twitter System Design)

• Design a simplified version of Twitter with APIs for posting tweets, following/unfollowing users, and fetching timelines.
