Welcoming questions
Can you tell us about yourself and the digital channels you have owned?
What to look for: A strong answer names specific channels with budget or results ownership, not just channels the candidate assisted on.
Sample answer: I have spent the last six years in B2B marketing, most recently owning paid search, paid social, and email for a logistics SaaS company. I managed around 40k dollars a month in ad spend across Google and LinkedIn and ran the lifecycle emails in HubSpot myself. Before that I was more of a generalist, which taught me enough SEO and analytics to keep our tracking honest.
Which campaign delivered your best ROI, and what made it work?
What to look for: Listen for real numbers, an honest explanation of why it worked, and whether the candidate credits process and testing rather than luck.
Sample answer: A LinkedIn retargeting campaign built around a pricing comparison guide. It converted at roughly a third of our usual cost per opportunity because we only showed it to people who had already visited our pricing page twice. The insight came from a funnel analysis in GA4, not from the ad platform, and that taught me to start with the data before touching creative.
Role-specific and technical questions
How do you split a new quarterly budget across channels with limited historical data?
What to look for: Strong candidates describe a structured approach with reserve budget for testing and defined checkpoints; a red flag is defaulting to whatever channel they know best.
Sample answer: I would start from the business goal and work backwards: if we need pipeline this quarter, most of the budget goes to intent channels like paid search, with maybe 60 percent there. I hold 20 percent for the channel I believe in but cannot prove yet, and I set a two week checkpoint to kill or scale it. The remaining 20 percent covers retargeting and email, which are cheap and usually pay for themselves.
Walk us through your measurement setup: what do you track, and where does attribution break?
What to look for: A strong answer shows the candidate distrusts platform-reported numbers and can explain a specific attribution gap they have dealt with.
Sample answer: My baseline is GA4 with server-side tagging, UTM discipline enforced through a shared template, and pipeline data pulled from the CRM so I report on opportunities, not just leads. Attribution breaks in two places for me: dark social, where people share links in Slack or WhatsApp, and long B2B cycles where the first touch is months before the form fill. I handle that with a simple self-reported attribution field on demo forms, and it regularly contradicts the dashboards in useful ways.
Describe a conversion optimization test you ran: hypothesis, result, and rollout.
What to look for: Look for a clear hypothesis, a valid sample size, and what changed afterward; a red flag is a test story with no numbers or no follow-through.
Sample answer: We suspected our demo form was too long, so my hypothesis was that cutting it from seven fields to four would lift completion without hurting lead quality. I ran it as a 50/50 split for three weeks until we had about 1,200 sessions per variant. Completion went up 22 percent and sales confirmed quality held, so we rolled the short form out to every landing page and added the removed fields to post-booking enrichment.
How do you evaluate whether an agency is doing a good job on paid media?
What to look for: Strong candidates tie agency evaluation to business outcomes and account hygiene, not just the agency's own reports.
Sample answer: I judge them on three things: movement in cost per opportunity rather than cost per click, the quality of their testing log, and how they behave when something goes wrong. I also keep admin access to every ad account and audit it quarterly, checking search terms, wasted spend, and whether changes in the change history match what they claim in the monthly deck. A good agency welcomes that audit; a defensive one is usually hiding neglect.
Which tools are in your daily stack, and what does each answer for you?
What to look for: Look for tools mapped to specific questions or decisions, which shows the candidate uses them deliberately rather than listing logos.
Sample answer: GA4 and Looker Studio tell me what happened on the site and in the funnel, and the CRM tells me whether it mattered to revenue. Google Ads and LinkedIn Campaign Manager are for daily spend checks, and Hotjar answers why a page underperforms when the numbers alone cannot. For email and automation I have mostly worked in HubSpot, and I keep a plain spreadsheet as my testing log because it forces me to write hypotheses down.
How do you keep lead quality visible to marketing, not just lead volume?
What to look for: A strong answer includes a feedback loop with sales and at least one metric downstream of the form fill.
Sample answer: I report on marketing sourced opportunities and closed revenue by channel, not just MQLs, which means the CRM integration has to be solid before anything else. I also sit in on a sales pipeline review every other week; hearing reps describe bad-fit leads in their own words changes your targeting faster than any dashboard. In my last role that loop got us to pause a display campaign that looked great on cost per lead but had produced zero opportunities in two months.
Behavioral and culture fit questions
Tell us about a campaign that flopped. When did you know, and what did you do?
What to look for: Look for early detection, honest ownership, and a concrete lesson; a red flag is blaming the platform, the agency, or the creative team.
Sample answer: We launched a top-of-funnel video campaign that I was convinced would build our retargeting pool cheaply. Ten days in, view rates were fine but the retargeting audience it fed converted worse than cold traffic, which told me we were attracting the wrong viewers entirely. I cut it at 40 percent of planned spend, wrote up what happened for the team, and the lesson stuck: engagement metrics mean nothing until you see what the audience does next.
Describe a disagreement with leadership over marketing priorities. How was it resolved?
What to look for: Strong candidates show they can push back with data while staying committed to the final decision, even one they disagreed with.
Sample answer: Our CEO wanted to shift most of the budget into brand awareness right when our pipeline coverage was thin. Rather than argue in the meeting, I built a one-page model showing what the pipeline gap would look like in 90 days under each scenario, and proposed a split: 70 percent stayed on demand, 30 percent went to the brand test with agreed success metrics. He took the deal, the brand test actually performed decently, and we expanded it the following quarter with everyone aligned on why.
How do you keep learning as platforms and algorithms change?
What to look for: Look for specific habits and a recent example of applying something new, not a vague list of newsletters.
Sample answer: I keep a small monthly test budget, usually 5 percent, that exists purely to try things I have read about, because I do not trust a tactic until I have run it on my own account. When Google pushed Performance Max, I ran it against our standard search campaigns for six weeks before forming an opinion. I also stay close to two peer communities of B2B marketers, which surface platform changes weeks before the official announcements reach me.
Problem-solving and case questions
Cost per lead doubled in a month on your main paid channel. Walk us through your diagnosis.
What to look for: Strong candidates diagnose systematically, separating tracking issues, funnel issues, and auction issues before touching campaign settings.
Sample answer: First I would rule out measurement: did tracking break, did a form change, is the doubling real. Then I split the metric, because cost per lead is cost per click times click-to-lead rate, and each half points somewhere different. If clicks got expensive, I check auction insights for a new competitor or a seasonality spike; if conversion dropped, I look at landing page changes, page speed, and lead quality mix. In a similar case last year the culprit was a consent banner update that silently killed a third of our conversion tags.
We give you an extra 30 percent budget for one quarter. Where does it go and how will you prove it worked?
What to look for: Look for a plan that defines success metrics upfront and resists spreading the money thinly across everything.
Sample answer: I would not spread it evenly; incremental budget should go where marginal returns are still positive, so first I check which channels are capped by budget rather than by audience. Realistically I would put most of it into scaling our best performing search campaigns and one concentrated bet, probably a new segment on LinkedIn. Proof means agreeing the metric before spending: incremental opportunities against the prior quarter baseline, reported with the same attribution method so nobody can move the goalposts.
Organic traffic is growing but demo requests are flat. What do you investigate?
What to look for: A strong answer questions the composition of the traffic before proposing conversion fixes, showing the candidate thinks about intent, not just volume.
Sample answer: My first question is what kind of traffic is growing. If it is all informational blog content ranking for broad terms, flat demos might be expected, so I would segment conversion rate by landing page and query type in Search Console. If high intent pages are growing but not converting, that points to a page or offer problem, and I would look at what changed on those templates. Often the fix is not a better button but a better path: adding a relevant next step to blog posts instead of pushing a demo on someone who is three stages too early.
