Hi All,

I want to thank Leetcode community and want to contribute back to the community with my experience with Google. I wont be posting the questions to respect NDA. But will provide details or similar questions on what to expect.

By the time I had given telephonic interview, I have solved 100 Leetcode questions mostly easy(20%) and medium(80%).
Telephonic Interview [27 June 2020]

Interviewer asked 2 questions. 1st one was easy to medium on two pointer and 2nd one was medium question on graph.

1. Harder than but similar to this https://leetcode.com/problems/intersection-of-two-arrays-ii/
2. https://leetcode.com/problems/course-schedule-ii/

By the time I had given virtual onsite interview, I have solved 200 Leetcode questions mostly medium (80% )and hard(20%).
Onsite Interview[24 August 2020]
Interview 1:

1. Given parabola on the x ang y axis you need to find the value of x where y is maximum. You have a predefine function which will tell you if the y is on increasing side or on peak or on the decreasing side.
2. gfg/path-rectangle-containing-circles/ way harder than this.

I didn't perform in this interview well. I have solved the question but couldn't get time to write the code. interviewer was fine but not very friendly and matured or experiened.

Interview 2:

https://leetcode.com/problems/longest-increasing-path-in-a-matrix/
Interviewer was very friendly. Interview went well. I have solved and written the code in 35 min.

Interview 3:

Interviewer was very friendly. Interview went well.

After 15 days I got to know that HC has approved my profile.

Note: None of the questions were from leetcode but pratcising questions on leetcode helped a lot. I have subscribed for premium and solved 80% question of google interview questions.

Interview Preparation Tips:
I want to give just one advise quality over quantity. Solve same question atleast twice if first time you didn't solve it in one go. Learn the concept from each question and revise it.

For Googlyness round, I have prepared these questions:

1. Tell me an area where you think you can improve.
2. Tell me about a time when you received critical feedback from someone.
3. Walk us through a time when you helped a customer through a difficult process and what that looked like.
4. Give me an example of when you took a risk and it failed.
5. Tell me a time when you created an innovative product.
6. Tell me about a time when you observed two business opportunities to improve ROI, and how did you determine that they were connected.
7. How do you find the time to stay inspired, acquire new knowledge, innovate in your work?
8. Tell me about a time when you had to deal with a poor performer on your team.
9. Tell me about a time when you could have stopped working but persisted.
10. Tell me about a time when you proposed a new business.
11. Describe how you would handle a busy situation where three people are waiting for help from you.
12. Tell me about a time where you thought of a clever new way to save money for the company.
13. Tell me a time when you earned trust of a group.
14. Tell me about a time when you had to dive deep into the data and the results you achieved.
15. Tell me about the most difficult interaction you had at work.
16. Tell me about a time where you overcame an obstacle and delivered results.
