Industry: Engineering and Manufacturing Department: AAD (Autmotive Aftercare Division) Job Title: Process Engineer

What are the best and worst things about your job?

I've been able to really get an idea of what role a process engineer has within the site. I've also dealt with many different opportunities within my role and have been able to feel like my work is of importance and validity to the site. I've also been on 4 weeks total of training which has been amazing and I've gained skills through the training that I can hopefully apply later on when back in university. I was also able to go around the UK and visit the other 3M sites which was a great opportunity to see if there are any other sites I'd potentially like to work at.

Interview Advice:

Telephone interview: prepare for normal competency type questions (name a time when...)
Group exercise: Contribute when you have good ideas. Don't be the quiet one, nor be dominant and difficult.
Technical interview: You cannot really prepare for these. Just think (logically!) and communicate your best ideas.
Behavioural interview: as per telephone interview.

Application Advice:

Try to be as well-rounded as possible, working in supply chain is almost impossible if you have no inter-personal or social skills. Good grades are important but if you can also show you do other activities outside of your degree such as being a member of societies/volunteering etc. this will separate you from the people applying that only have good grades on their CV and not much else.

Interview Advice:

Be personable and friendly, and talk about your greatest achievements in both your academic career and outside of this. The questions I was asked were generic interview questions such as 'what are your greatest achievements', 'give us an example of when you overcame a challenge', 'what attracted you to this role'. My advice would also be to google typical interview questions and come up with brief answers for a variety of questions that you could then elaborate on if they are asked in the interview. Think of particular moments that you could talk about during your life when you've had to work with difficult people or you've overcome a difficult module etc. as these particular stories can be tailored to suit a variety of questions. Also do a little bit of research into the company itself as this will show a valid interest in the company. Look at their about us/ethics pages as these should give you facts about the company that you could mention during your interview, thus showing you have an interest in 3M.

Application Advice:

Show your passion for the role and the field which it is in, for example marketing, finance etc.

Interview Advice:

Be yourself! Your personality is just as important as skills. Employers look for the right fit within the team, so showing your personality is key.
Also using 'real work' examples, instead of university examples, when answering behavioural questions is more favoured and is what the employer is looking for.

Similar to above. Enjoy the interview. It is more about the interviewer learning about you as a person. They are not there to judge. They are there to assess how you think and whether that will gel in the role that you have applied for. Just be yourself, if you get the job they expect the person in the interview to be the same that comes to work everyday.

Interview Advice:

Be yourself - 3M put a lot of stock in your 'fit' with our culture and team and the only way we can see that is if you showcase who you really are. We don't want you to act as someone you think we want you to be.

Application Advice:

The usual stuff really. Research the company and tailor your appliction to the role that you are applying to.
One thing to realise is that 3M is an incredibly diverse company with an enormous product mix. Nobody will expect you to go into detail about various 3M products. It's enough to know that 3M has a huge range of products in many different industries. Maybe learn the different industries that 3M is involved in though.
Healthcare, Electronics and energy, personal safety etc.

Interview Advice:

Relax and enjoy the day. It's quite informal and in a way kind of enjoyable. Also try to be geniune.

Application Advice:

I can't really advise - I applied after completing a placement with 3M previously and had a brief interview and no assessment centre. I'd say it is an honest company and no-one tried to trick you - it is probably best for you to be honest also. The company is pretty good at picking the right people for what they want so you are either a good fit or you aren't.

Interview Advice:

I had very normal interview questions - nothing tricky or unusual. You'll be interviewed for the engineering scheme by potential supervisors and regional experts so they will know what they want from their engineers.

Optimised Operations Engineer, Inhalation Technical Group at 3M

Application Advice:

Be yourself, be honest and be open. Only apply for a role like this if it is truly what you want to do as it will come across if you don't. Try to gain some business experience before doing so even if it is working in a retail shop.

Interview Advice:

All questions are based around evidence so be prepared to provide evidence on every question. This can either be in your personal life, education or work experience. Work experience is always the preferred. Questions are often around leading a team, overcoming a problem, communication skills, working under pressure etc. The biggest advice I could give is that everyone is personable and try and show a bit of your personality.

Optimised Operations Engineer, Manufacturing technology at 3M

Best:

3M provided me with 4 weeks of training which I think is really great. They're also a large, global company but I like the fact that they are committed to working ethically. There are also options to travel within the UK and potentially further abroad if necessary which I think is also a good trait.

Worst:

I can't really think of any negative traits about 3M as a company. They are a large, global company and so it can at times make the work feel impersonal but this is relatable to any large manufacturing company.
Probably the worst thing about 3M is the lack of gender equality/diversity programs they have. They are committed to many great causes such as improving their sustainability and investing in local communities but having and supporting a diverse workforce I feel is integral to the continuing improvements of 3M as a company. Having people from varying backgrounds challenges all of us to alter the way we think and is important to show that anyone can work at 3M.
