Qualcomm Test Engineer interview questions

New grad interview. Was pretty simple coding round, one round on communication technologies, behavioral round and technical analysis round. Interviewers were quite smart but asked only simple questions to gauge my thinking process

One of the worst recruiter experience I ever had. There were two recruiters coordinating with me to schedule interviews. Recruiters never responded to my email. Even they did not send me a rejection email until I followed up two times in two weeks. Then they sent me an auto generated email. I completed all the stages including final panel interview. Few interviewers were asking very specific questions that only product developers should be able to answer even though it is a test engineer position. Felt like they were looking for software developer at test engineer salary.
