At such times, you’ve got to step up and be a good friend by helping them to get better at their career and also generally in life too.
1. Help them build a strong resume

A brief resume with no grammatical errors can bag them a good interview call. Help them build a strong resume first. Add their achievements and skill sets, if they haven’t already.
2. Endorse them on Linkedin

Professional networking sites are important too. Endorsing them for the skills they are good at would look great on their profile.
3. Recommend them to your network

If your network is good, ask people around whether they need people. And, if there are vacancies, recommend your friend’s name for them.
