I interviewed at Pubmatic Baner office from pool campus drive in which a pen-paper test was conducted which consist of both aptitude and technical section, and the last section was programming where we have to write a program and a SQL query. The test also consisted of negative marking scheme, so be careful before ticking the answer. After a week or so the results were declared and I was shortlisted for F2F interview at their office. There were 2 technical interviews followed by a managerial interview on the same day, so be prepared for staying till late in the company, I finished my managerial interview at 9:30 pm. If you have cleared all the round you will receive a mail or call for HR within 3-4 days. The overall process was quite good and was focused on the technical part for me it was testing they gave me various scenario and told to write test-cases and check the testing mind of the candidate.
