The median is 4 listed stages across 43 ordered stage lists in our company registry. The range is 2 to 7, and four is the most common count.
That is a description of our summaries, not a standardized count of interview sessions. The sample includes partial candidate reports and general company hiring frameworks whose FDE applicability may be uncertain. Read the scope on the company page before planning around a number.

The registry contains 111 companies. Entries without stages are excluded. We also exclude menus of possible formats, such as Perplexity's technical interviews, because a candidate does not necessarily take every format the company publishes.
The October 7 addition is Retell AI's senior US role, whose posting lists four stages. The last stage itself combines a technical interview and a team conversation.
The October 5 sweep, integrated on October 9, added Deployment Inc's two-stage hiring-challenge route and reduced xAI from six stages to four stages of general company guidance. It also reclassified Distyl AI and McKinsey QuantumBlack as menus of formats, which this count excludes.
A stage is not an interview session
A recruiter call may count as one stage. A panel with several interviewers may also count as one. A take-home can add substantial work without adding another conversation. Comparing stage counts without these details can mislead a candidate about the time commitment.
The September review also changed some entries from detailed candidate reconstructions to narrower employer-published frameworks. The resulting median moved from five to four listed stages. This is a change in our evidence and summaries; it does not establish that employers shortened their interviews.
Prepare from the format and its rules
For coding, establish whether you will work in a shared editor, modify an existing codebase or build a project. For design, establish whether the interviewer expects system architecture, a customer workflow or an ambiguous decomposition problem. For customer discussions, clarify whether the exercise is a presentation, role-play or account of prior work.
Tool rules can change within the same loop. A company may allow AI during a build and restrict it during another assessment. Read the instructions for the named round rather than inferring permission from the employer's product.
Our coding questions, system design questions and customer and behavioral questions cover transferable preparation. The Palantir decomposition guide develops one particular format; it is not evidence that every employer uses it.
Ask for a schedule you can plan against
Ask how many separate sessions are expected, their duration, whether a take-home is included and which stages are conditional. That gives you a more useful workload estimate than a four-stage or six-stage label.
Check the evidence behind the schedule as well. An employer guide can describe a company-wide framework without confirming your team's exact exercise. A first-person account can describe one candidate's experience without establishing what happens at another level or location. Those distinctions explain why the source notes and confidence labels sit beside the interview details.
Method
We count nonempty ordered stage lists in our structured interview data and exclude entries marked as a menu of formats. We do not normalize the granularity of each summary or claim all lists are complete. Figures are current as of October 9, 2026 and recomputed during validation. This is a registry statistic, not a measured average across candidates.

FAQ
Our 43 ordered stage lists have a median of four listed stages and a range of two to seven. Four is also the most common count, appearing in 15 entries. These are registry summaries, including partial and general-company guidance, not a survey of completed FDE interviews.
The longest ordered summary in our registry has seven stages. That does not identify the employer with the most interview hours: a single panel stage may contain several separate interviews. Ask for the actual schedule.
No. One stage may combine several interviews or a substantial project. Compare expected hours, assessment formats and preparation instructions rather than the number of rows in a summary.
Coding, design, decomposition and customer discussions are useful preparation areas, but the refreshed sources do not support claiming that every FDE loop includes the same rounds. Start from the role-specific invitation.
Discussion (5)
The distribution is more useful than the median here. The stage counts depend on how each entry groups its interviews, so I would use the company-specific scope before comparing them.
Agreed, and the convergence is on the mix rather than the count. What changed is that the decomposition round stopped being a Palantir peculiarity and became standard. That is the round to prepare for regardless of whether the loop is four stages or seven.
Reader question: when a company says five rounds, does that include the recruiter screen or not?
Usually yes, and that is why comparing two companies' round counts is less informative than it looks. One will count the recruiter call and a take-home as stages, another will describe the same process as three interviews. We record each company's own framing rather than normalizing them, and the method note at the bottom says so.
The two-stage loops deserve a warning label. I went into one expecting a light process and the second stage was a paid full-day build treated as a real customer deliverable. Fewer stages, far more work per stage.
