The telecom round focused on SMPP, SS7, and relevant 3GPP standards related to MSISDN and IMSI. The coding interview included two medium-level LeetCode problems — Ocean View and a PWD (Print Working Directory)-style function. The analytical round centered on troubleshooting approaches and problem-solving methodology. The cross-functional interview (30 minutes) covered behavioral topics such as handling feedback, prioritization, and collaboration. The hiring manager interview was engaging and enjoyable. Although the recruiter mentioned that I performed strongly in four rounds and “okay” in the coding round, and that I was still being considered, I eventually received a rejection after a month of waiting.
