I applied online. I interviewed at Trabus Technologies (San Diego, CA)
Interview
Starts with an initial phone screening that confirms you are a US citizen; then, proceeds to a technical + behavioral interview with the team; then, finishes with a weekend coding challenge.
It was straightforward process. I got an offer after one interview. The company is still very old school but the interviewers were really nice and welcoming. They are a really small company but are slowing expanding.
