Applied through the Dell portal. The recruiter then called to discuss an initial screening, followed by four rounds of telephone calls (3 technical + 1 manager). The calls were scheduled with different panels one after the other.

The interview process was clearly conveyed to me and scheduled properly. Interviewers were helpful, offering hints and working with me while navigating code. They were also open to discussion. Overall, it was a very good experience.
