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.”

Research eradicates bacteria from avocado facility

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
