I went through three rounds of interviews, totaling over seven hours.

This included two one-hour phone interviews, followed by a five-hour in-person onsite interview. The onsite portion involved four one-hour interviews, with two Jane Street employees present per session. The questions were highly technical and related to specific issues the company has experienced historically.

Definition questions on AV terminologies and technologies.

Define HDCP, a DSP, how multicast works, DHCP, EDID, etc.

Root problem-solving ability questions. These involved highly specific scenarios that have been experienced onsite. Some often took months for them to resolve. A fully realized solution to resolution is expected in a matter of minutes.

Example: Troubleshoot a single bright sign player not showing Bloomberg from an internal IPTV server.

How would you fix a system design where an additional mic was needed, but the hardware did not support it?
