The interview process takes 4 weeks on average.

Stage 1: An initial phone screen with HR
The recruiter will call to discuss the candidate's job interests, location preferences, they will outline the entire process and suggest study materials for preparation
Stage 2: A 1 hour technical phone interview.
This coding session includes basic questions about previous projects and solving a coding problem in a google doc.
Stage 3: An onsite interview consisting of 5 interviews
The onsite interview has 5 rounds plus one lunch interview. The questions are organized into 3 categories - Coding, Design and Open ended questions and interviewers are required to make sure all these categories are covered thoroughly. In each technical interview the candidates talk to one engineer and solves technical problems on a whiteboard. At the end the of the interviews, the interviewers submit their reviews to a hiring committee, which has the final say on the offer. One thing several candidates mention is that referrals by a current Google employees, can get you past the technical screen and directly to onsite.

The interview process takes 2-4 weeks on average.

Stage 1: Initial phone screen by HR.
Stage 2: A technical phone interview.
The interview usually involves a link to a Google Doc where the candidate is expected to solve a coding problem.
Stage 3: Occasionally a take home project can be assigned between the technical phone screen and the onsite, but not always.
Stage 4: An onsite interview.
The onsite usually includes 4 separate interviews with questions about stats, coding, and data analysis

The interview process takes 4 weeks on average.

Stage 1: Initial phone screen by HR.
Stage 2: One or two technical interviews with a hiring manager or a designer.
This includes deep dive into the candidate's portfolio, a detailed resume review and sometimes an app critique. If these interviews are well done, next is a design challenge/test (choose from three scenarios and design solutions to the problems described).
Stage 3: The onsite interview.
The onsite consists of a two part design presentation to a group of about 8-10 designers from different teams across Google. The first part of the presentation is the design challenge and the second part is presenting a project from the candidate's portfolio. After the presentation session there is a series of one on one interviews with the same designers that the candidate presented to that morning. In total there are about 6 one on one interviews which include mini design challenges, technical and behavioral questions.

The interview process takes 2-4 weeks on average.

Stage 1: Initial phone screen by HR.
Stage 2: A technical interview with a Product Manager. The questions are mostly general, then centered around a theoretical problem.
Stage 3: An onsite interview consisting of 5 45 min interviews, 4 product focused interviews with product managers and 1 technical interview with an engineer.
