*referral tips*

You've heard and seen plenty of tips on requesting referrals.
Let me share how I evaluate them as a Senior Programmer at Kantar 🔽

☑️ Match skills to the job: I focus on whether the candidate’s skills and experience align with the job requirements.

☑️ Check the referrer’s insights: Strong referrals come with specific examples and detailed insights about the candidate.

☑️ Culture fit: I also look at whether the candidate’s values and working style align with our team and company culture.

☑️ Growth potential: Enthusiasm for the role and signs of growth potential are great indicators of future success.

I appreciate it when candidates make it easy for their referrer by providing detailed resumes and clear project highlights. It shows preparation and respect for everyone's time.

Remember, while referrals are valuable, they're just one part of the job search process. If your skills are weak, any referral strategy won’t work.

If you’re struggling with this, then platforms like Preplaced can connect you with experienced SDEs.
