Newbie here

Hi Grapeviners, I have 1.5 years experience on manual testing,jira ticket management. I have learnt adv java(jee,jdbc,java servlets, multi threading), spring boot, MySQL,mongodb, javascript, reactjs and microservices, git. I have developed online shopping web application project. I want to learn more for java backend developer role. Please suggest new technologies. Can anyone pls suggest how to start applying for jobs and giving interviews.

Its been 3 months since I left my last company after completing 8 months of internship, I rejected the full time offer because I was exploited and work culture was very toxic, since then I applied to more than 100+ jobs online and hardly converted 5 interviews and got 1 offer for part time which is soon going to be revoked, assuming from the company's behaviour. At this point I have lost all the motivation to work, improve and apply for jobs I am tired and drowing in self doubt. It even kills me to see the people who are not skilled as I am are getting good jobs and salary. With all this my family is not so supportive and not a single day has passed where I didn't get into arguments with my parents.

Other than standard platforms like Linkedin,Naukri. What apps do you use to keep an active watch on job opportunities? Pls also mention any tips and tricks

Twitter dm, LinkedIn, naukri.com any other? The point is I'm trying to look for the hiring but most of the time don't get the response. Where do you or your friends find the jobs mostly?

Im looking for job in product management, need help guys

Hi guys I'm a campus hire, 1 year experience. I want to switch to a different domain. I see people switching from my company to much better offers but I can't really ask them because my managers may hear about it. Do you guys apply to jobs via linkedin? Directly to company website? Via referrals? Are there jobs that aren't listed on company websites? Pls help a noob out, any guidance is GREATLY appreciated. I really want to switch careers asap.
