It was a Walkin but only for the selected ones. Initially they asked us to wait in a hall, they called us on 9 but started the process on 10:30. Even they started very late, they didnt have any sequence of calling the candidates. They have mixed up all of the resume and randomly they were calling us. I supposed to be in first batch but unluckily i was in last batch. They had 2 technical interview and last was the HR round. HR asked the Google questions like your strength and weakness. why you want to change your job and expected package. They didnt give me offer letter at the moment instead they told Interview process is complete and we will email you shortly.
