I am a fresher who is looking job for Data Analyst/business Analyst.
Please provide information if anyone knows jobs on this post.
This is my field but I don't know what a "fresher" is (I am in the UK). If you are a new graduate, your best bet is a graduate role/programme. You do need to keep your programming languages up-to-date but also get actual work experience - coding is often a good place to start or even IT support but something that demonstrates that you know how a workplace works, can show up everyday and actually have experience working with internal and external stakeholders, build relationships etc.
New graduates will not be able to go straight into BI analytics unless they're in a "graduate" role or had lots of industry experience and then got qualified later.
Have you tried Google, Indeed, LinkedIn, or Simplyhired?
