Google SWE 2025 Intern - Interviews

I recently had my two interviews for a Software Engineering Internship at Google for Summer 2025. Here’s how they went:

1. First Interview:
   • I completed the first question perfectly and efficiently.
   • The interviewer then gave me a "follow-up" or continuation question. My initial solution partially worked but didn’t cover all edge cases. I explained my approach and had a clear plan to address the remaining cases, which was relatively straightforward, but I ran out of time before I could fully implement it.
   • It felt like the continuation question might have been improvised because I finished the first one quickly. Does that sound plausible?
2. Second Interview:
   • I completed everything and implemented a working solution.
   • The interviewer suggested a small adjustment, saying it would make the solution slightly better, though my original approach had the same time complexity and was also valid.

Now I’m wondering:

• Based on your experience, what are my chances of passing?
• How much weight is given to the follow-up question I didn’t fully code in the first interview, given that I explained the solution and the necessary adjustments?
• How long does it usually take to hear back after the interviews?

Any insights or similar experiences would be greatly appreciated!
