Mock Interview
UFS students shine with confidence at the 2025 Mock Interview Day, ready for career success.

To get senior and postgraduate students ready for the world of work, the University of the Free State (UFS) Division of Career Services’ Placement Preparation Day, which was initiated in 2023, has grown into an annual workshop – Mock Interview Day – with this year’s event taking place in the Callie Human Centre on the Bloemfontein Campus.   

Held on 14 and 15 May 2025, this UFS initiative – aimed at addressing employability – has evolved through the implementation of several educational subdivisions tasked with the responsibility of assisting all registered students understand the professional environment. One of these divisions is the Centre for Teaching and Learning’s (CTL) ‘Graduate Attributes’ – an initiative that seeks to assess a student’s development of valuable attributes during lectures.

According to Belinda Janeke, Assistant Director of Career Services, “Feedback indicates that most students have no interview experience – a critical factor. It is through these mock interviews that students’ confidence is built and their transition from student to employee is smoothened.” 

With the assistance of staff members and employees in conducting the interviews, the two-day initiative has seen evident success in both attendance and reach. “Yesterday we had about 90 students come in for the mock interviews and all of them stated that it was their first time being interviewed,” said Janeke. “Even though our office is situated on the Bloemfontein Campus, we also visit the South and Qwaqwa campuses to ensure accessibility across all three UFS campuses,” Janeke added. Emphasising results, she shared that in the 12 years she has been working in this division, student engagement has grown due to improvements in technology. 

Career Services sends out letters and emails on the 11th of each month to recognise the achievements of students who have used their services. In collaboration with the UFS’ Vision 130, more directions are being explored across the three campuses, starting with the cross-campus Shoe Camp project.

This initiative targets all UFS students, prioritising senior individuals on the cusp of job hunting. “As a postgraduate student, I am looking into getting a job next year and I have never been interviewed before, so I needed the trial run to get more information on accurate interview etiquette,” said Aphiwe Mbutuma, an Administration honours student. Mbutuma said the support she received from the staff was crucial in boosting her confidence for her next interview. She further described the experience as an eye-opener, adding that students should seize these opportunities to understand what is expected of them. Zukile Daki, a second-year student in the Faculty of Law, said: “I once bombed an interview, so I came here to improve, and it went well.”

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
