Exceptional, People-First Organisation. I can’t recommend this BA transition training organisation highly enough. From day one, it’s clear that they are genuinely people-focused and truly care about your growth and success. You don’t just receive excellent training, you get full, ongoing support that makes the entire journey feel less daunting and more empowering.

What really sets them apart is the sense of family they create. You’re encouraged, supported, and never made to feel like you’re navigating the transition alone. It’s more than a training programme; it’s a community that invests in you every step of the way.

Incase you’re wondering, yes I have made the transition and I now work as a business analyst.

Hi, my name is Kelvin Guobadia. I joined Next Gen without really knowing what to expect, especially after attending several training platforms in the past that didn’t work out for me. At the time, I was working as a tester and had some business analyst knowledge, but I lacked the confidence to attend interviews.

Next Gen came at exactly the right time. I had an upcoming interview where I was required to deliver a presentation. After sharing my presentation with Dr B and the team, it became clear that it needed a lot of improvement. I really needed this job, as the company I was working for had gone into bankruptcy. Although I had already completed BA training and had a solid foundation, I needed guidance to truly stand out.

Dr B and the team gave me clear feedback on what to improve. I updated the presentation and shared it again – Dr B even stayed up most of the night reviewing my corrections. Their support and belief in me gave me the confidence I lacked, as I previously came across as quiet and unsure of myself. Dr B told me straight away, “The job is yours.”

I went into the interview confident, delivered a strong presentation, and got the job. I also had three other interviews lined up, and with the confidence from the first one, I secured all of them. In the end, I was able to choose the role I wanted.

Honestly, Next Gen is God sent – a community that genuinely cares. I hope you join and see you at the top ✌️

A truly supportive organisation. I was introduced to NextGen through a friend who couldn’t recommend them enough, and true to his words, they are a very supportive community. In 2024, they supported me with interview preparation without even knowing me personally.
The coaches took their time to review my responses and provided detailed, constructive feedback.

I continued attending their free sessions and interview prep to keep learning while applying. When I later needed to retrain to rebuild my confidence after previous interviews, NextGen supported me again through live projects and a positive, encouraging learning environment.

What truly sets NextGen apart is their interview support. The coaches genuinely give their time, attention, and encouragement to prepare and support candidates, especially those switching careers or aiming to secure roles.
I highly recommend NextGen. In fact, I already have, to many people within my space. Their support and desire to see people succeed set them apart.
