This was the worst interview experience ever with the worst company. Everyone only had a very short interview, literally 10 minutes long. They ultimately selected candidates based on grades. The work culture is also terrible. They selected 12 students, and all of them had interviews of 10 minutes or less. I was interviewed in October.
