- It centers on coding and algorithm problems often using an online coding tool.
Onsite Interviews (Technical Rounds):
- You’ll go through several rounds (often 4-6) with different team members.
- These include coding tasks, system design questions, and other technical tests.
Behavioral Interviews:
- These aim to evaluate how well you fit with Google’s culture and core values.
- You’ll face questions about your background how you solve problems, and your ability to work in a team.
Final Decision and Offer:
- After you’ve done with your Google interview, the people who talked to you discuss how you did.
- If you make the cut, you’ll get an offer, which often comes with detailed feedback.
Technical Google Interview Questions
Google’s technical interviews are tough and aim to check your ability to solve problems, write code, and understand tech concepts. Here’s what you should get ready for in 2024:
Key Topics to Study:
- Data Structures: Arrays linked lists, stacks, queues, hash tables, trees, graphs.
- Algorithms: Sorting, searching dynamic programming greedy algorithms, recursion.
- System Design: Scalability, load balancing, caching, databases distributed systems.
- Coding Challenges: Real-world coding problems to test your skills.
Example Questions and Detailed Answers:
- Arrays and Strings:
- Question: Create a function to identify the longest substring without repeated characters.
- Answer:
def length_of_longest_substring(s: str) -> int:
char_set = set() # Set to keep track of unique characters in the current window
left = 0 # Left boundary of the sliding window
max_length = 0 # Variable to store the maximum length of substring found
for right in range(len(s)):
# While the character at `right` is in the set, move the `left` pointer to the right
while s[right] in char_set:
char_set.remove(s[left])
left += 1
# Add the current character to the set
char_set.add(s[right])
# Update the maximum length of substring found
max_length = max(max_length, right – left + 1)
return max_length
- Trees and Graphs:
- Question: Develop a function to verify if a binary tree is balanced.
- Answer:
dclass TreeNode:
def __init__(self, val=0, left=None, right=None):
self.val = val
self.left = left
self.right = right
def is_balanced(root: TreeNode) -> bool:
def height(node):
if not node:
return 0
left_height = height(node.left)
right_height = height(node.right)
if left_height == -1 or right_height == -1 or abs(left_height – right_height) > 1:
return -1
return max(left_height, right_height) + 1
return height(root) != -1
- Dynamic Programming:
- Question: Find a solution to the “coin change” problem.
- Answer:
def coin_change(coins: List[int], amount: int) -> int:
dp = [float(‘inf’)] * (amount + 1)
dp[0] = 0
for coin in coins:
for x in range(coin, amount + 1):
dp[x] = min(dp[x], dp[x – coin] + 1)
return dp[amount] if dp[amount] != float(‘inf’) else -1
