You have completed your electrical installation training. Now comes the interview — and for many technical students, this is the most unfamiliar part of the job search process. These tips specifically address what electrical installation employers in Kenya look for and how to present yourself confidently.
Research the Employer Before the Interview
Before any interview, research the specific employer. For electrical installation roles, understand: does the company do residential, commercial, or industrial work? Are they primarily a contractor or do they have employed in-house technical staff? Do they work with solar installations, security systems, or other specializations? This knowledge lets you ask informed questions and demonstrate genuine interest — something most entry-level candidates fail to do.
Documents to Bring
Always bring to an electrical installation interview: your KNEC certificate (original and copies), your NITA trade test certificate if obtained, your national ID, a brief CV (even one page is sufficient), any reference letters from your TVET college or previous employers, and your driving license if you have one (many site jobs require driving). Arriving with organized, original documents signals professionalism.
Technical Questions to Prepare For
Kenyan employers interviewing electrical installation graduates commonly ask:
- What is the difference between single phase and three phase power?
- What size cable would you use for a 15-amp circuit?
- Explain what a residual current device (RCD) does.
- How do you test a circuit before energizing it?
- What is the Kenya Wiring Code and why does it matter?
- Describe the steps you would take to isolate a circuit for maintenance.
Practice your answers to these questions until you can explain them clearly and confidently without hesitation.
Safety Knowledge Is Tested
Electrical installation employers will assess your safety awareness in interviews. Know: personal protective equipment (PPE) requirements for electrical work, lockout/tagout procedures for isolating circuits, the difference between earthing and bonding, safe working distances from live conductors, the importance of testing before touching, and the basic emergency procedures for electrical shock treatment. Demonstrating strong safety knowledge reassures employers that hiring you will not create liability.
Practical Tests
Some employers conduct brief practical assessments as part of their hiring process — identifying cable types by color code, demonstrating how to make a connection, reading a basic wiring diagram, or using a multimeter. Practice these basic practical skills before interviews. Being able to competently demonstrate even simple tasks builds confidence in your technical capabilities.
Questions to Ask the Interviewer
Asking good questions at the end of an interview signals genuine interest and professionalism. Good questions for an electrical installation role include: What types of projects would I be working on in the first six months? What safety training do you provide for new employees? Is there opportunity to develop specialist skills like solar or security systems? What does career progression look like at this company? These questions show you are thinking about a career, not just a paycheck.
