DexCare DevOps Engineer Interview: Questions & Prep (2026)

DexCare is a digital health company that helps large hospital systems manage patient demand, scheduling, and virtual care delivery. For a DevOps engineer, this means building cloud infrastructure where real patient data lives, which puts HIPAA compliance, SOC 2, and HITRUST controls at the centre of daily work, not at the edges.

As of July 2026, knok's job radar shows 8 open roles at DexCare across DevOps and related engineering tracks. Job postings for this role commonly list AWS as the primary cloud platform, with Kubernetes, Terraform, and CI/CD automation also coming up frequently. The interview process typically covers cloud infrastructure design, container orchestration, secrets management, and how you handle compliance in a regulated environment. Candidates report a mix of technical rounds and a behavioural or culture-fit conversation. Coming prepared with concrete examples from compliance-aware or healthcare-adjacent environments will set you apart immediately.

These questions come up repeatedly in DexCare DevOps interviews, based on the role's focus on healthcare cloud infrastructure and platform reliability:

1. Walk me through a CI/CD pipeline you built or owned end-to-end. What tools did you choose and why?
2. How have you managed secrets and credentials in a cloud environment with strict compliance requirements?
3. Job postings mention AWS heavily. Describe your hands-on experience with EKS, ECS, or Fargate and when you would choose one over another.
4. How do you design infrastructure for high availability in a system where downtime directly affects patient access to care?
5. Tell me about a production incident you led. What was your process from the first alert through the post-mortem?
6. How do you structure Terraform modules for a large engineering team? What goes in a module and what does not?
7. What does HIPAA compliance mean for your day-to-day DevOps decisions? Give a concrete example.
8. How do you monitor a distributed microservices system? Which metrics do you watch most closely and why?
9. A developer's deploy breaks the staging environment late at night. Walk me through exactly how you handle it.
10. How do you balance shipping quickly with keeping security controls intact in a regulated environment?
11. Describe your approach to container image security: scanning, hardening, and runtime controls.
12. How have you identified and acted on infrastructure cost reduction opportunities without hurting reliability?

Q: Tell me about a production incident you led.

*Situation:* The patient scheduling service at my previous company went down on a Monday morning, affecting appointment bookings across a large hospital network client.

*Task:* As the on-call DevOps lead, I needed to find the root cause, coordinate the fix, and keep both engineering leadership and the client success team informed within our SLA window.

*Action:* I pulled CloudWatch logs and traced the failure to a misconfigured health check on our ECS service that was terminating healthy tasks after a recent deployment. I rolled back the task definition to restore traffic, opened a dedicated Slack channel to give stakeholders status updates every few minutes, and documented every action in our incident log. Once the service was stable, I ran a blameless post-mortem and we added a pre-deployment health-check validation step to the pipeline.

*Result:* Service was fully restored within our SLA window. The post-mortem change blocked the same class of failure in all subsequent releases. The client team specifically mentioned the clear communication in their feedback survey.

Q: How do you structure Terraform for a large team?

*Situation:* At my previous company, six product teams were all touching the same Terraform monorepo, which caused frequent state lock conflicts and accidental cross-team changes.

*Task:* I was asked to redesign the repository structure so teams could work independently without stepping on each other.

*Action:* I introduced a layered pattern: a shared 'platform' layer for VPCs, IAM roles, and the EKS cluster owned by the platform team, and per-team 'service' layers with their own isolated state files in S3. I built a versioned reusable module library so teams could consume platform primitives without copying code. I also set up Atlantis to enforce PR-based plan and apply with mandatory peer approval before any changes could go through.

*Result:* State conflicts dropped to zero within the first two sprints. Teams reported faster, more confident deploys, and the module library was adopted as the standard across the entire engineering org.

Q: What does HIPAA compliance look like in your day-to-day DevOps work?

*Situation:* At a healthtech startup, we were onboarding our first enterprise hospital client who required a HIPAA Business Associate Agreement and a full technical review of our AWS environment.

*Task:* I had to audit our infrastructure and close all compliance gaps before the review, with about six weeks on the calendar.

*Action:* I ran AWS Config rules and Security Hub to get a baseline of findings. The biggest gaps were S3 buckets without default server-side encryption, CloudTrail not enabled in all regions, and RDS instances with backup retention below the required window. I wrote Terraform to enforce encryption at rest across all data stores, enabled CloudTrail at the organisation level, and corrected the RDS backup settings. I also wrote a runbook covering access review cadence and breach notification steps.

*Result:* We passed the technical review with zero critical findings. The hospital client signed the contract within two weeks of the review completing.

Keep STAR answers tight. DexCare interviewers move through technical rounds quickly. Aim for 2-3 minutes per behavioural answer: one sentence each for situation and task, most of your time on action, and a clear result. If you have no specific metric, describe the qualitative outcome ('the client renewed', 'no recurrence in the following six months').

Lead with the healthcare context when it applies. If a question touches on security, reliability, or compliance, connect your answer to what those things mean when patient data or care access is at stake. That framing shows you understand DexCare's domain, not just generic DevOps.

For system design questions, think out loud. Name the AWS services you would use, explain the tradeoffs (why EKS over ECS for this workload, for example), and call out where compliance controls fit: encryption, audit logging, network segmentation. Interviewers want to follow your reasoning, not just hear the final answer.

For 'how do you handle X' questions, be specific about tooling. 'We used Prometheus and Grafana with PagerDuty for on-call routing' is far stronger than 'we set up monitoring.' Name the tool, describe how you configured it, and mention one thing you would do differently with hindsight.

Compliance instinct, not just compliance knowledge. Anyone can recite HIPAA bullet points. DexCare wants engineers who automatically think about audit logging, least-privilege IAM, and encryption at rest when designing a new service, before a security review needs to flag it.

Real AWS depth. Surface-level cloud knowledge will not hold up under probing. Expect questions that test whether you know the operational tradeoffs between services: EKS versus ECS versus Lambda, RDS versus Aurora, CloudWatch versus a third-party observability stack. Have concrete examples ready for each.

Incident ownership. DexCare's systems directly affect patient care. Interviewers look for candidates who stay calm in outages, communicate clearly to non-technical stakeholders, and run structured post-mortems rather than assigning blame.

Collaboration with product engineers. DevOps at DexCare is as much a platform and enablement role as it is an ops role. Show that you have worked alongside developers, helped them ship faster, and built self-service tooling rather than acting as a gatekeeper.

Genuine curiosity about the healthcare domain. You do not need clinical expertise. Showing that you understand why uptime, data integrity, and access control mean something different in a healthcare context makes a strong and lasting impression.

Week 1: AWS and Kubernetes depth.
Revise EKS cluster management, ECS task definitions, IAM roles for service accounts, and VPC design. Build one Terraform project from scratch: a multi-AZ VPC with private subnets, an EKS cluster, and an RDS instance with encryption enabled throughout. Hands-on practice beats reading documentation alone.

Week 2: Compliance and security layer.
Read the AWS HIPAA compliance whitepaper, available on the AWS website. Practice explaining how CloudTrail, AWS Config, and Security Hub work together as a compliance layer. Know what a HIPAA Business Associate Agreement means for the infrastructure decisions you make daily.

Week 3: CI/CD and observability.
Map out a CI/CD pipeline you have built or would build for a containerised microservice. Be ready to explain every stage: build, test, security scan (Trivy or Checkov), push to ECR, deploy via ArgoCD or Helm. Prepare your monitoring story: what you alert on, how you reduce noise, and how you run post-mortems.

Week 4: Behavioural stories and practice.
Write out 4-5 STAR stories covering: an incident you led, a time you improved developer experience, a compliance or security challenge, and a time you disagreed with a technical decision and how you resolved it. Practice saying them out loud and ask a peer to push back on vague answers.

Day before: Check DexCare's LinkedIn page for recent product announcements or engineering updates. Prepare two specific questions about their on-call culture and platform roadmap to ask at the end of each round.

If you want to stay active in the market while you prepare, knok checks 150+ job sites nightly, applies to jobs that match your resume, and messages HR for you, so you do not miss a relevant opening while your focus is on interview prep.

Giving generic DevOps answers. Saying 'I set up a Jenkins pipeline' without explaining what problem it solved, why Jenkins over alternatives, or what you would change today, tells the interviewer very little. Always attach the 'so what.'

Ignoring the healthcare context. Candidates who treat DexCare like a standard SaaS company miss the point of the role. If you never mention compliance, security controls, or the impact of downtime on patient care, you signal a mismatch with the team's priorities.

Overstating AWS depth. Interviewers probe quickly. If you claim EKS expertise but cannot explain the difference between a managed node group and a Fargate profile, trust breaks immediately. Be honest about where your depth ends and your breadth begins.

Rushing to solutions in system design. Jumping straight to 'I would use Kubernetes' without first clarifying scale, traffic patterns, and compliance requirements reads as pattern-matching rather than engineering judgment. Ask a scoping question or two before you start designing.

Not preparing questions to ask. Candidates who arrive with nothing to ask signal low engagement. Prepare 2-3 specific questions about on-call rotation structure, how the platform team works with product teams, or how compliance reviews are handled for new feature launches.
