Experience 1: E4 SWE - Selected ✅

Role: Software Engineer E4
Location: Menlo Park
Date: November 2024
Experience: 3 years

Phone Screen (45 min)

Problem: Subarray Sum Equals K

def subarray_sum(nums, k):
    count = 0
    prefix_sum = 0
    prefix_counts = {0: 1}

    for num in nums:
        prefix_sum += num
        count += prefix_counts.get(prefix_sum - k, 0)
        prefix_counts[prefix_sum] = prefix_counts.get(prefix_sum, 0) + 1

    return count

Follow-up: What if we need the actual subarrays?

Onsite Day

Coding 1 (45 min):

• Merge Intervals
• Solved optimally, discussed edge cases
• Follow-up: What if intervals are streaming?

Coding 2 (45 min):

• Valid Palindrome II
• Quick solution, then optimized
• Interviewer asked about testing strategies

System Design (45 min):

• Design Facebook News Feed
• Discussed: Ranking algorithms, caching, real-time updates
• Trade-offs between consistency and availability

Behavioral (45 min):

• Time you moved fast and broke things
• Conflict with manager
• Most impactful project

What Worked

1. Speed: Solved problems quickly with time for follow-ups
2. Communication: Thought aloud throughout
3. Impact stories: Had quantified impact examples ready

Experience 2: E3 New Grad - Selected ✅

Role: Software Engineer E3
Location: Seattle
Date: October 2024
University: UC Berkeley

Phone Screen

Problem 1: Two Sum
Problem 2: Valid Parentheses

Solved both quickly, discussed time/space complexity.

Onsite

Coding 1: Binary Tree Vertical Order Traversal

• Used BFS with column tracking
• Clean implementation

Coding 2: Random Pick with Weight

• Binary search on prefix sums
• Discussed probability distribution

Behavioral:

• Why Meta?
• Time you failed and learned
• Team collaboration example

Tips

• Meta moves fast - practice solving quickly
• Have 5-6 behavioral stories ready
• Show enthusiasm for Meta’s mission

Experience 3: E5 SWE - Rejected ❌

Role: Staff Software Engineer E5
Location: New York
Date: September 2024
Experience: 7 years

Where I Struggled

System Design: Design Instagram

• My design was solid technically
• But I didn’t discuss trade-offs enough
• E5 requires deeper architectural reasoning

Behavioral Gap:

• Didn’t demonstrate enough cross-team influence
• E5 requires showing leadership beyond coding

Lessons

1. E5 bar is high: Need to show leadership, influence
2. Trade-offs matter: Discuss why you chose each approach
3. Scale focus: E5 designs need to handle Meta scale (billions)
