Possible disadvantages

    Exercises are primarily text-based without interactive or visual learning aids, which might be less engaging for some users.
  • Dependence on Volunteers
    The platform relies heavily on volunteer mentors, which can lead to delays in getting feedback and may affect the consistency of support.
  • Interface Complexity
    Some users find the interface and workflow somewhat complex and unintuitive, particularly for those new to the platform.
  • No Real-Time Collaboration
    Lacks real-time collaboration features, meaning users cannot code together or get instant feedback.

Questions & Answers

As answered by people managing Exercism and Colloqa.

What makes your product unique?

Colloqa's answer:

Colloqa rehearses the whole conversation, not a list of questions. The AI counterpart behaves like the person you are about to face: an interviewer who follows up on the weak part of your answer, a negotiator who does not move off their number, someone who reacts emotionally rather than reasonably. It can also swap seats and play the candidate, so a hiring manager can practise running the interview.

  • Four scenarios in one tool: job interviews, negotiations, difficult conversations and interviewing a candidate as the hiring manager
  • Voice or text in 12 languages, and you can switch mid-conversation
  • Every session ends with coaching: what worked, what fell apart and the one thing worth drilling next, plus a skill profile tracked from session to session

Why should a person choose your product over its competitors?

Colloqa's answer:

Choose Colloqa if you want to say the words out loud before they count, not just read a list of likely questions.

  • One tool for the conversations that decide something: job interviews, salary and other negotiations, difficult conversations at work or at home, and the hiring manager's side of an interview
  • The AI pushes back on what you actually said, instead of moving to the next scripted question
  • 12 languages, voice or text, in the browser with nothing to install
  • Free tier with one full session a day and no credit card; paid plans are Weekly $8.99 or Monthly $19.99, cancel anytime

What we do not claim: an AI counterpart is a sparring partner, not a prediction of the room you are walking into, and automated feedback can be wrong. What rehearsing reliably does is make the words familiar before they matter.

How would you describe the primary audience of your product?

Colloqa's answer:

People with a conversation coming up that decides something, and who want to rehearse it rather than only think about it:

  • Job seekers preparing for an interview, from retail, healthcare and customer service to finance, sales, software engineering and administrative roles, including behavioral ("tell me about a time") interviews
  • People about to negotiate a salary, a raise or a job offer, and founders preparing an investor pitch
  • Anyone facing a difficult conversation: giving feedback to a report, handling an angry customer, a hard talk with a partner
  • New hiring managers who want to practise interviewing a candidate

It is built for individuals practising on their own, in any of 12 languages.

What's the story behind your product?

Colloqa's answer:

There is a strange gap in how we prepare for high-stakes talking. An athlete trains the movement. A musician plays the piece before the concert. Someone with an interview on Thursday reads a list of common questions on their phone and calls that preparation.

Reading an answer and saying it are different skills. The gap shows up as the sentence that came out backwards, the number you did not hold, the point you meant to make and did not. Colloqa exists to close that gap in the cheapest possible place: a rehearsal where nothing is at stake.

It started with job interviews and grew to negotiations, difficult conversations and the hiring manager's side of the table, in 12 languages. The people who build Colloqa also run it, so the person reading your support email is the person who can fix the thing.

Which are the primary technologies used for building your product?

Colloqa's answer:

  • Web app: React, running in the browser (nothing to install)
  • Backend: Supabase (Postgres, auth and edge functions), hosted on Vercel behind Cloudflare
  • Speech: Google Cloud Speech-to-Text and Text-to-Speech
  • Conversation and feedback: Google Gemini
  • Marketing site: Next.js
