Google New Grad Virtual Onsite: Four Coding Rounds and BQ

Role: Software Engineer, New Grad
Result: Final outcome not disclosed
Report time: September 2026
Application: Applied online

Timeline

The candidate applied in September of the previous year and received the OA around April 2026. Google contacted them about the virtual onsite roughly two to three weeks after they completed the OA.

The virtual onsite contained four rounds. Each round combined behavioral discussion with coding.

Coding round 1

Find a shortest substring to delete from a string of length n so that the remaining string contains only distinct characters.

A commenter asked whether the deleted section must be contiguous and whether the remaining prefix and suffix are concatenated. The candidate did not answer, so those details remain unresolved.

Practice: Shortest Deletion for a Distinct Remainder

Coding round 2

The second problem was a variation of Number of Islands. The source did not preserve the variation's exact rules.

Practice: Number of Islands

Coding round 3

The candidate had to implement two or three object-oriented methods for finding files inside a collection of files.

Practice: Search a File Collection

Coding round 4

The final problem was a calculator that supported parentheses. The source did not preserve the complete operator set or input grammar.

Practice: Calculator With Parentheses

Behavioral interview

The behavioral questions focused on team projects and other standard teamwork topics.

In a follow-up comment, the candidate said they had prepared many tree problems but none appeared in the loop. The onsite location was asked about but never clarified.
