  1. Two minutes

    Name, email, what you want to work on and the times that suit you. Everything else is optional.

  2. A personal reply

    I check my calendar and confirm by email whether I am free at those times, or suggest the closest ones.

  3. No commitment

    This form takes no payment, and asking does not oblige you to book.

What we practise.

  • Interview preparation: behavioural and technical answers, explaining past projects and trade-offs, the question you did not expect.
  • Presentations and demos: opening well, walking through a technical argument, answering hard questions.
  • Meetings and workplace communication: stand-ups, disagreeing respectfully, feedback, steering a discussion.
  • Professional writing: email, Slack, specs and documents with precise, natural wording.
“Thanks to Mack's interview prep, I was able to successfully pass my interview! His advice is incredibly helpful, especially for those preparing to work in the U.S. or with American companies.”

Tell me a little about you and the times that suit you. I read every inquiry myself.

Days, times and your time zone, for example “Tuesdays or Thursdays after 7pm ICT”. I will confirm if I am free.
For example a role you are interviewing for, a talk, or a meeting that feels hard.
