At Google, the interview process begins with a recruiter reaching out after reviewing your resume.

If your qualifications are promising, you might skip the initial screening interview. Following a discussion with the recruiter, they schedule a technical interview about four weeks later.

To prepare, Google provides resources focusing on data structures and algorithms, emphasizing practice with LeetCode questions.

The first phone technical interview lasts about 45 minutes and typically involves two questions: an easier one to start and a more challenging follow-up. It's important not to linger too long on the initial question, as I learned firsthand; managing time effectively is key.

Unfortunately, after the process concludes, feedback arrived about a week later. While I didn't progress to the next rounds, the experience offers invaluable insights for future attempts. Good luck!
