Apparently the tech job market is crazy. I started applying 2 weeks ago. Majority of the applications aren't even viewed. So far, I have had only two recruiter calls. Both didn't proceed since they were looking for hands on in particular areas. And I got a few rejection emails too.(Not sure if they are the usual automated Applicant Tracking System generated rejections or someone indeed looked at it). I fear my career in the software field is over. Questions.1. Can we say the market good only for junior developers? How good/bad is it for the experienced ( 20+ years) individual contributors?2. Is the job search worth the effort?. Would it be a better idea to learn some skills and start building something on your own?3. My profile is decent and I work for a reasonably reputed company. But my linkedin profile is empty since I am not comfortable with others viewing my profile. (Mentioned only the company names, start date etc).  So I havent had any recruiter reach me directly. Nor did I contact any recruiter. Any general tips on resume/getting noticed ( Without updating linkedin profile)?PS: I received tons of calls from recruiters for jobs in the service based companies. But I am looking at product based companies only. Also, I do understand that networking/referral will help. But I dont have a good network.
