How to Conduct Reference Checks for Remote Candidates

The Case for Maximal Referencing of PMs: In a past job, I worked with two product leaders with equal skill in building products. But they had completely divergent skills in hiring. One hired phenomenal PMs. They quickly grew to be company-wide favorite PMs due to their strong viewpoints. The other hired on paper phenomenal PMs. But they just weren’t right for the company. It’s not really a surprise the first got promoted - and the other left for greener pastures. 𝗥𝗲𝗳𝗲𝗿𝗲𝗻𝗰𝗲 𝗰𝗵𝗲𝗰𝗸𝘀 𝗮𝗿𝗲 𝘄𝗼𝗿𝘁𝗵 𝘁𝗵𝗲 𝘁𝗶𝗺𝗲 One of the practices the first hiring manager swore by was lots of reference checking. She was a master of back channel reference checking throughout the interview process. And her reference checks were notoriously long. The other just did one reference check after he had already decided he was giving out the offer. 𝗢𝗻𝗲 𝗼𝗳 𝘁𝗵𝗲 𝘁𝗵𝗶𝗻𝗴𝘀 𝘁𝗵𝗮𝘁 𝗺𝗶𝗴𝗵𝘁 𝘀𝘂𝗿𝗽𝗿𝗶𝘀𝗲 𝘆𝗼𝘂 𝗺𝗼𝘀𝘁 𝗮𝗯𝗼𝘂𝘁 𝘁𝗵𝗲 𝗵𝗶𝗿𝗶𝗻𝗴 𝗺𝗮𝗻𝗮𝗴𝗲𝗿 𝘄𝗵𝗼 𝗱𝗶𝗱 𝗾𝘂𝗶𝘁𝗲 𝘄𝗲𝗹𝗹 𝗶𝘀: 𝘚𝘩𝘦 𝘦𝘷𝘦𝘯 𝘥𝘪𝘥 𝘳𝘦𝘧𝘦𝘳𝘦𝘯𝘤𝘦 𝘤𝘩𝘦𝘤𝘬𝘴 𝘣𝘦𝘧𝘰𝘳𝘦 𝘱𝘢𝘴𝘴𝘪𝘯𝘨 𝘢 𝘤𝘢𝘯𝘥𝘪𝘥𝘢𝘵𝘦 𝘧𝘳𝘰𝘮 𝘩𝘪𝘳𝘪𝘯𝘨 𝘮𝘢𝘯𝘢𝘨𝘦𝘳 𝘴𝘤𝘳𝘦𝘦𝘯. I, too, have found it works really well. Nowadays, I’ve started to do these reference checks at three stages. Let’s break this approach. 𝗖𝗵𝗲𝗰𝗸 𝟭 - 𝗦𝗰𝗿𝗲𝗲𝗻𝗶𝗻𝗴 𝗦𝘁𝗮𝗴𝗲 Committing to a conversation with a candidate means I’ll also tap into: • Previous workplace colleagues • Mutual connections Direct collaborators get a call, a brief 10-minute check-in. My aim here is to pinpoint standout candidates that I really want to push through. 𝗖𝗵𝗲𝗰𝗸 𝟮 - 𝗣𝗼𝘀𝘁-𝗜𝗻𝘁𝗲𝗿𝘃𝗶𝗲𝘄 𝗦𝘁𝗮𝗴𝗲 The second reference check I like to do is post-interview. I’ll use this to 𝘷𝘦𝘵 𝘵𝘩𝘦 𝘢𝘤𝘤𝘶𝘳𝘢𝘤𝘺 of what people said in the interview. If the pass this second reference check, they’re almost ready to hire. 𝗖𝗵𝗲𝗰𝗸 𝟯 - 𝗣𝗿𝗲-𝗢𝗳𝗳𝗲𝗿 𝗦𝘁𝗮𝗴𝗲 The third and final reference check is the one most companies do. But I like to focus it on supervisors and skip levels. All PMs need to make an impact on leadership. This is the only round I actually use references supplied by the candidate. Everything else is back-channels. 𝗜𝘁 𝗺𝗮𝗸𝗲𝘀 𝗮 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝗰𝗲 “𝘉𝘶𝘵 𝘈𝘢𝘬𝘢𝘴𝘩, 𝘐’𝘷𝘦 𝘨𝘰𝘵 𝘵𝘩𝘳𝘦𝘦 𝘳𝘰𝘭𝘦𝘴 𝘵𝘰 𝘧𝘪𝘭𝘭 𝘵𝘩𝘪𝘴 𝘲𝘶𝘢𝘳𝘵𝘦𝘳!” I know that it seems a lot of work to add two stages of reference checks to your process when you probably only have the pre-offer stage right now. The thing is, getting your hiring right makes you much more impactful. But getting them wrong really hurts you.

Every hiring manager should make time for reference checks, especially for leadership roles or those heavily requiring soft skills. While interviews offer insights into a candidate’s background and skill, they only provide one side of the story. Reference checks provide an external perspective, allowing you to make more informed hiring decisions. I recommend asking candidates for references and also seeking out objective references they may not directly provide. Schedule at least 30 minutes to ensure plenty of time to ask questions. Before the call, do some research on each reference’s relationship with the candidate, how long they worked together, and their professional connection. Top 5 Reference Check Questions 1. Why do you think the candidate chose to leave your company? This question offers valuable insight into the candidate’s motivations and career aspirations. It can also provide the other side of the story if the exit from the previous company was at all contentious. I prefer to work with people who do their best to leave places in good condition and not burn bridges. 2. Is this person one of the top 5 people you’ve ever worked with? Why? Ranking forces specificity and offers a clearer sense of how this candidate measures up. I find this more insightful than simply asking if they’d work with the person again, as it provides a more direct assessment. If a candidate provides a reference that does not absolutely put them in their top 5 that is a red flag. 3. What’s one area this person improved in while working with you? I put a lot of weight on a candidate’s ability to grow and adapt. This question can reveal how quickly they enhance their value on a team. It’s often helpful to follow up by exploring the process they undertook to improve and how much help the team or company provided. 4. Can you give an example of a time they made a difficult decision or tackled a tough problem? This question is essential for assessing resilience and problem-solving. It’s important to hear about specific challenges the candidate handled, which reveals their grit and determination. I really look for an example of the candidate doing a hard thing that helped the team or company succeed. 5. What was the best thing about working with them? And the most challenging? Unlike traditional strengths and weaknesses questions, this phrasing highlights the candidate’s impact as a teammate. It can reveal aspects of their work style, personality, and how they interact and communicate with others. I love to hear that a candidate is a joy to work with because of their positive attitude, which often has nothing to do with their skill in the role. BONUS: What did you learn from them, and what did they learn from you? I love this question because it often brings out unexpected answers. It reveals the candidate’s openness to feedback and their potential for growth. I want to work with people that are coachable and love to learn, but also enjoy teaching others.

This Controller aced every interview. But a 5-minute reference call revealed the truth. Here's why references can make or break a hire… References aren't just a box-ticking exercise - they're often the final piece of the puzzle. (I learned this lesson early in my recruiting career.) I was working with a prestigious financial firm who had their sights set on a “perfect” Controller. He’d sailed through six rounds of interviews, and the offer was practically drafted. But then came the reference check. All it took was a simple question to his ex-manager. "Would you rehire this person?" The silence down the line said everything. Technical ability is one thing, but work style, communication pattern, and ability to handle pressure are important, too. Yet issues in these areas rarely surface during structured interviews. That’s why I always approach references in two ways: 1️⃣ Early-stage reference discussions with candidates themselves. When I ask, "Can you get good references from your last employer?" their response (hesitation, excuses, body language) warns me about potential red flags. 2️⃣ Formal reference checks with previous employers. These aren't about verifying employment dates. They're about understanding the person behind the resume. I dig into their real strengths, working styles, and potential blind spots. The single most revealing question, "Would you rehire this person?" cuts through the niceties and gets straight to the truth. In a world where AI can polish resumes and candidates can rehearse interview answers, authentic human perspectives are irreplaceable. The best hires aren't just technically capable - they're the complete package. And sometimes, only a reference can tell you if you've found one.
