Landing an SDR role in 2026 comes down to one moment: the mock cold call. Hiring managers test whether you research like a rep, open with a trigger rather than a pitch, ask questions, and take feedback on the spot. Prepare that call the way you would prepare a real one, and the rest of the interview takes care of itself.

What hiring managers actually test

We have sat on both sides of SDR interviews, for our team and for customers' teams. Three things decide most of them.

1. Can you be brief and structured? Two minutes on who you are, with a beginning, a middle and a point. The job is 30-second openers; a ten-minute answer disqualifies.
2. Will you survive the dip? A story about something hard that took months, with a routine in it. "I trained every morning for a year" beats "I pulled an all-nighter".
3. Are you coachable? Tested live: they give you feedback on your mock call and ask you to do it again.

Everything else, the CV, the degree, the previous title, is tie-break material.

Research the company like an account

Treat the company as a prospect. Thirty minutes is enough.

• The persona. Who do they sell to? Read two case studies and write down the job title that appears in both.
• The trigger. What happened at the company in the last 90 days: a funding round, a new country, a VP Sales hire, a product launch. That is your opener for the interview itself.
• The sales team. Look at how many SDRs and AEs they have on LinkedIn and how long they stay. A team where SDRs become AEs in 15 months tells you the path is real.
• The product in one sentence. Your own words, as you would say it to their persona, not the homepage's.

Use the trigger in your first message to the hiring manager. "I saw you opened Germany in September, I assume that means outbound from scratch" is an SDR sentence. "I am very motivated by your mission" is not.

Prepare the mock cold call

Most companies send a short brief the day before. If they do not, ask for one: the persona, the product in five lines, and one fact about the fictional account. Then build the call on what the data says works.

The 1,000,000-call benchmark Sonik built with Quentin Despas (Katana) on French B2B cold calls shows 65% of reps open by explaining what they sell, and those calls convert 2-3% of conversations into meetings. Openers built on a trigger convert 7-10%. So do not open with the product. Open with the fact in the brief and ask for 30 seconds.

Then ask questions that start with "how": they lift conversion by 190% in the benchmark. "How do you handle this today?" is the whole discovery you need in a mock call.

When the interviewer objects, and they will, do not answer. Ask "What do you mean?" first (+197% in the benchmark). It shows you listen, and it buys you the real objection.

Close by asking for a specific slot: "Thursday at 10 or Friday at 4?" Then stop talking.

Practise it out loud, five times, with someone playing a rude prospect. Record one and listen to your opener. If you hear the product name in the first sentence, start again.

Tell your numbers with context

If you have sales numbers, give them with the team average next to them. "Twelve meetings a month against a team average of nine" means something; "I was top performer" does not. If your numbers were uneven, say why and what changed: a new list, a new opener, a tool change.

If you have no sales numbers, use any number with a routine behind it: calls made in a fundraising job, tables turned per shift, hours trained per week. Managers hire for the routine, not the industry.

Questions to ask them

Your questions are part of the test. Ask the ones a rep would ask.

• How many conversations a day does your best SDR have, and with which dialer?
• What share of SDR meetings do AEs accept?
• What are the written criteria to move to AE, and when did the last SDR make the move?
• Who reviews calls, and how often?
• What do the first 30 days look like?

A manager who cannot answer the third one is telling you the path is not real. That is useful to know before you sign.

Close and follow up

End the interview like a call: "Based on this, is there anything that would stop you from moving me to the next step?" Listen to the answer; it is the objection you need to handle in your follow-up. Send a short note the same day, three lines, mentioning one thing from the conversation and confirming interest. No essay.

If they send a rejection, ask for one piece of feedback. The ones who reply are worth staying in touch with; the seat reopens in six months.

How Sonik approaches SDR interviews

For our own team, and for customers who ask, the mock call runs on Sonik itself: a 20-minute session with a prepared list and a trigger per contact, so we see how a candidate handles a parallel-dialing rhythm and a real connect rather than a scripted role play.

The session is scored on the same four points as a live call, opener type, "how" questions, objection handling and the close, then we give two notes and run it again. What we hire on is the difference between the first and second run.

Conclusion

Research the company like an account, open the mock call with a trigger, ask "how" questions, say "What do you mean?" to the first objection, and take the feedback visibly. This week, write a 30-second trigger opener for the company you want to join and say it out loud ten times. It is the interview.
