Interviews in South Africa walk a fine line between gathering essential information and violating a candidate’s constitutional rights. The country’s progressive labour laws—rooted in the Employment Equity Act, the Labour Relations Act, and the Constitution—explicitly protect job seekers from discrimination. Yet many hiring managers still ask questions that are not only inappropriate but outright illegal.
Understanding what you cannot ask is just as important as knowing what you should ask. Ask the wrong thing, and you risk a CCMA case, reputational damage, and losing top talent. This guide breaks down the prohibited topics every South African employer must avoid.
Protected Grounds Under South African Law
South Africa’s legal framework prohibits discrimination based on a wide range of personal characteristics. The Employment Equity Act (No. 55 of 1998) and Section 9 of the Constitution list these protected grounds:
- Race, gender, sex, pregnancy, marital status
- Ethnic or social origin, colour, sexual orientation
- Age, disability, religion, conscience, belief
- Culture, language, birth, and family responsibility
Any question that directly or indirectly seeks information about these grounds is unlawful unless it can be proven to be an inherent requirement of the job. This is an extremely narrow exception.
Specific Questions That Are Off-Limits
Let’s look at the most common illegal interview questions and why they are problematic.
Family and Marital Status
“Are you married?” / “Do you plan to have children?” / “Who takes care of your kids?”
These questions are always illegal in South Africa. They imply discrimination based on marital status, pregnancy, and family responsibility. Even asking a woman about her plans for children is a red flag—it suggests you might not hire her because she could take maternity leave.
What to ask instead: Focus on availability and commitment. For example, “This role requires occasional weekend work. Are you able to meet that requirement?” This is a job-related question that does not pry into personal life.
Age
“How old are you?” / “When did you graduate?” / “Are you nearing retirement?”
Age discrimination is prohibited for both older and younger workers. Asking for a birth date or graduation year can be used to infer age. Even seemingly innocent questions like “How many years of experience do you have?” are acceptable, but asking “When did you start working?” can be problematic.
What to ask instead: “Do you have the physical stamina required for this manual role?” (if it’s a genuine requirement) or “Tell me about a time you adapted to new technology.” These are skills-based, not age-based.
Disability and Health
“Do you have any disabilities?” / “What medical conditions do you have?” / “Have you been on sick leave often?”
You may only ask about a candidate’s ability to perform the essential functions of the job. Asking for a blanket disclosure of disabilities is illegal. The Employment Equity Act requires employers to make reasonable accommodation.
What to ask instead: “This role requires standing for long periods. Is there any reasonable accommodation we can provide to help you perform these duties?” This invites the candidate to discuss needs without forcing disclosure.
Race, Ethnicity, and Origin
“What is your race?” / “Where are you from originally?” / “Your surname is Xhosa—are you Xhosa?”
Direct questions about race or ethnicity are prohibited unless you are conducting lawful affirmative action or Employment Equity reporting. Even then, you should not ask in an interview—that data is collected separately and voluntarily. Questions about language or accent can also cross the line if they are used to exclude. For guidance on this, read our article on How to Handle Language & Accent Questions Legally & Fairly.
Religion and Belief
“What church do you go to?” / “Do you observe any religious holidays?” / “What is your political affiliation?”
Religion, belief, and political opinion are protected. You cannot ask about these unless it is a genuine occupational requirement (e.g., a faith-based school hiring a teacher of that faith). Even then, the question must be carefully framed.
What to ask instead: “This role requires working on some Saturdays. Is that something you can accommodate?” The candidate can voluntarily mention religious constraints without you probing.
Salary History
“How much did you earn at your last job?”
While not explicitly illegal in all cases, asking for salary history is discouraged and may lead to pay discrimination. The focus should be on salary expectations for the role, not past earnings. The Employment Equity Act promotes equal pay for equal work, so anchoring pay to a previous salary can perpetuate historical inequities.

Gray Areas: Questions That Require Careful Phrasing
Not all sensitive questions are outright illegal—but they can become discriminatory if poorly worded.
Employment Equity and B-BBEE Status
Asking “Are you black?” or “What is your B-BBEE level?” during an interview is inappropriate. However, employers do need demographic data for EE reporting. The proper way is to collect this data voluntarily and separately from the interview process, anonymised where possible. For best practices, see Interview Questions Around Employment Equity & B-BBEE.
Relocation and Location
“You live in Soweto—how long will it take you to get here?” / “Do you have a car?”
Questions about where a candidate lives can subtly discriminate on the basis of race, class, or geographic origin. Instead, ask about reliability and transport in a neutral way: “This role starts at 7:00 AM. Are you able to arrive on time consistently?” If the candidate volunteers they rely on taxis, that’s their choice. For context, see Questions About Relocating Within South Africa (Township to City etc.).
Gaps in Employment
Asking about a gap is fine. But digging into the reason—e.g., “Were you fired?” or “Were you in jail?”—can be problematic if it probes into a disability or illness. Focus on what the candidate learned during the gap. For more, see Addressing Gaps Due to Studying, Family, or Taxi Strikes.
What You Can and Should Ask Legally
Good interviewing focuses on job-related competencies. You can legally ask:
- Work experience and skills relevant to the role
- Behavioural questions (e.g., “Tell me about a time you solved a conflict”)
- Scenario-based questions (e.g., “How would you handle a tight deadline?”)
- Motivation for applying and interest in the company
- Availability for specific work hours (if it’s a requirement)
- Ability to perform essential job functions (with accommodation discussion)
You can also ask about working in teams, especially diverse ones. This is a great area to explore. See Interview Questions About Working in Multicultural Teams for respectful ways to probe cultural competence.
Respectful Value- and Culture-Based Questions
Every company wants to know if a candidate will fit its culture. But this can easily slip into discrimination if you ask about personal values tied to religion, politics, or lifestyle.
Safe approach: Ask about workplace values. For example, “What kind of work environment helps you perform your best?” or “How do you approach teamwork and feedback?” These are neutral and job-related. For more, read Respectful Ways to Ask Value- and Culture-Based Questions.
The Consequences of Asking Illegal Questions
In South Africa, an illegal interview question can lead to:
- A complaint at the CCMA or Equality Court
- Damages for unfair discrimination
- Reputational harm and loss of trust
- Potential for the candidate to withdraw from the process
Moreover, the Labour Relations Act (Section 187) makes it automatically unfair to dismiss an employee on these grounds. Even if you don’t hire, a rejected candidate can claim discrimination if you asked prohibited questions.
Building a Fair and Lawful Interview Process
To stay compliant, follow these steps:
- Train hiring managers on the Employment Equity Act and Constitution.
- Standardise interview questions – use a structured, role-focused guide.
- Separate EE data collection – use a separate form after the interview.
- Document everything – keep records of questions asked and why.
- Review your own bias – regularly audit interviews for subtle discrimination.
Also, consider how your questions align with diversity and inclusion. See Interview Questions About Diversity & Inclusion in South African Workplaces for a deeper dive.
Final Thoughts
South African employers have a legal and ethical duty to interview fairly. Knowing what you may not ask is the first step. The next is shifting your focus to skills, behaviour, and potential—without crossing into personal or protected territory.
A well-crafted interview respects the candidate’s dignity while still assessing fit. When in doubt, ask yourself: Is this question directly and genuinely necessary to evaluate the person’s ability to do the job? If the answer is no, leave it out.
