Razorpay DevSecOps & Supply Chain Security interview questions

Easy to define and easy to fail. The scoring half is where each gate sits, what it does to build time, and the honest admission of what the whole set misses.

Workload authentication, traffic encryption and authorization need separate verification. Admission and RBAC constrain who can deploy a workload that bypasses those controls.

An incident response question wearing a Git costume. The wrong instinct is to rewrite history first, and it costs you the hour that matters.

Four tools that solve the same sentence and differ on one question: where does the plaintext end up? In a regulated environment that question decides the answer.

Most clusters fail an RBAC review on the same handful of patterns. Naming them concretely, plus the namespace-first design that prevents them, is what separates operators from tutorial readers.

Reciting injection classes you cannot fix is the trap. The scored move maps each risk category to a lever an ops or platform engineer owns, from response headers to metadata endpoints.

Tool selection is the shallow half of secrets questions. Senior answers live in the mechanics: dual-validity windows, consumer caching, and revocation you have actually tested rather than assumed.

A WAF matches patterns in HTTP and stops there. Know exactly which classes it catches, which it cannot see, and what closes the gap, because block-dashboard confidence is how breaches happen anyway.

Volumetric floods die at the anycast edge; everything else reaches your origin anyway. The origin leak, expensive endpoints and unproxied surfaces decide whether a CDN is armour or decoration.

Most insider incidents are boring: a departing engineer copies a repo, a contractor keeps a token. Buy hygiene rather than surveillance, and protect the culture that makes people report their own mistakes.

Choose by trust boundary, not fashion: mesh-issued mTLS inside a cluster, audience-bound tokens across teams and clouds, both together at scale. Static shared secrets are the thing being replaced.

The single highest-value security change available to most pipelines, and the reason it works is worth understanding rather than configuring. It removes the secret rather than protecting it.

Three terms that get used interchangeably and answer three different questions. The one that makes them operational is the admission rule at the end: no provenance, no deploy.

Everyone endorses least privilege; few can describe how they would measure over-permission across a fleet. The scoring answer names the evidence source, the tiered remediation, and the break-glass hatch that makes it survivable.

Naming the replacement is the floor of this question. What scores is the audit-then-warn-then-enforce sequence and an honest answer about the vendor chart you cannot fix.

The honest answer splits traffic containment from access control. Flat yes or no loses points here; the condition under which segmentation stops being theatre is what the interviewer wants.

Experienced answers are ordered and verifiable: minimal base, benchmark applied as code, identity and exposure next, then continuous proof it stayed that way. Checklists recited out of order are the tell.
