The Google interview process is very hard. Expect the questions to be difficult and specific to their operations. They are very keen on hiring people with good problem-solving skills, so get ready to be thrown open-ended questions or questions that require you to resolve a complex problem.
The good news is you can ace your job interview by preparing. Gather the possible questions that they might ask and prepare a short but straightforward answer. Practice speaking with clarity and organized thought. It’s also a good idea to get some mock interview experience from a trained career coach.
