Career, communication and interview coaching for technology professionals
Get the job, the promotion and the respect your work deserves
You already know your work. The hard part is showing it in English under pressure: in interviews, meetings, presentations, negotiations and client calls. I coach you to speak clearly, explain complex ideas simply and sound confident when it counts.

01 / The problem
It’s not just about knowing English. It’s about talking confidently about your work.
You can be very good at your job and still struggle to show it in English.
Maybe your interview answers run too long. Maybe you know the answer but can’t structure it quickly. Maybe you stay quiet in meetings, lose the room when you explain something technical, find senior stakeholders or client calls hard, or sound less confident than you really are.
I help you close that gap. We focus on the interviews and conversations that matter at work.

02 / How we work together
A clear plan, then practice until it feels natural
This isn’t passive learning. You practice the exact situations you’re struggling with, using your own material: the job description, your project, your slides, the meeting you’re worried about.
Real scenarios and feedback
Role plays of your interviews, meetings and calls, with targeted feedback and the language you need for your role and the teams you work with.
Progress against the plan
We check what has changed at work against the goals we set, and adjust the plan.
Inside every session
One technique
I explain one way of structuring what you say, or one piece of language.
Examples
You hear a strong version and a weak one, and why the difference matters.
Role-play
We act out your interview, meeting or conversation as realistically as we can.
Feedback
I tell you exactly what worked and what to change.
Second attempt
You do it again with the changes. This is where it starts to stick.
One thing to try
You leave with one thing to use at work before our next session.
Every bundle includes practice prompts and exercises. Personal setup of an AI practice partner is included in the full 25-session communication, interview and leadership programs. A free ChatGPT account works. See what’s included →

What changed for three clients
I’ve left their names out. Results depend on the job market and on your work, so I can’t promise you the same outcome.
These are my accounts of coaching engagements, with client names withheld. Platform reviews describe clients’ experiences; they do not independently verify these employers’ hiring decisions. Coaching cannot guarantee a job offer or promotion.

About me
I understand both sides of the room
I’m Mark Parfenov, a native English speaker. I spent more than ten years in sales, operations, program management and consulting, at Google, KPMG, EY, Caterpillar and Tufts University. That taught me that being technically strong is only part of moving up. You also need to explain your thinking clearly, influence people and show your value when the stakes are high. That’s what I coach.
Questions
Before you book
Should I start with English, interview preparation or career coaching?
Start with the situation you need to handle. If you struggle to explain your work in everyday meetings, start with communication coaching. If an interview is coming up, choose interview preparation. If the role or direction is unclear, start with career coaching. In the free consultation I help you separate language, communication and career needs and choose a focus.
AI is changing my work in tech. How do I explain the value I still bring?
Explain the decisions you own: how you define the problem, check an AI-generated solution, spot risks and connect the result to the business. In career coaching we turn that experience into evidence for your CV, interviews and promotion conversations. I cannot predict which jobs will disappear or promise job security. We work on how clearly you can demonstrate your judgment and contribution.
Is this English tutoring?
No. The focus is how you perform at work, not textbook English. We work on the situations that affect your career: interviews, meetings, presentations and conversations with senior people. Your English improves because you practice exactly those.
Do I need advanced English?
No. Coaching is for people who already work in English and want to communicate more clearly and confidently. For communication coaching, intermediate (B1) is enough. For interview and leadership coaching, you’ll get the most out of it at B2 or above. Not sure? Take my free Mini English test.
Do you work with technical professionals?
Yes. Most of my clients work in tech: engineers, product managers, analysts, designers and their managers. We work on the things they actually face, like explaining a design decision, a status update to stakeholders or a system-design interview.
Can you help with job interviews?
Yes. We work on how you structure your answers, your stories, behavioral questions, explaining technical work, how you come across, and mock interviews.
Is this useful if I already speak English fluently?
Yes. Many of my clients don’t need language lessons. They need to be more precise, more structured and more convincing, especially with senior people.
How long does coaching take?
Sessions come in bundles of 5, 10, 15 or 25. A bundle of 5 or 10 suits one clear goal, like an interview coming up. The full program is 25 sessions: two a week for about 12 weeks. We agree the right size in the free consultation.
Is the consultation really free?
Yes, and there’s no obligation. We talk about your goal, I tell you honestly whether coaching makes sense, and we agree on a plan only if you want to go ahead.
What currency are your prices in?
Prices are charged in EUR; UK clients can request a GBP invoice. USD, PLN and GBP display conversions are estimates. If a live rate is unavailable, prices stay in EUR. Your invoice confirms the final total and any applicable tax before you agree.
Can my employer pay for coaching?
Yes. I can give you receipts and invoices for reimbursement, and a contract on request. Companies can also book one of my corporate programs.
