+## Simulation Log Viewer
+
+    nuTonomy runs simulations of different car builds in different scenarios. Even if the car build and scenario match, the results can differ. Your task is to create a web interface that presents the scenario logs and performs basic operations.
+
+## Requirements
+
+1.  Every scenario has an id and a maximum number of "stops" (times when the car unexpectedly braked).
+
+2.  Every simulation run has a start time, end time, car build and a corresponding scenario. A run is considered successful if
+
+- It does not exceed the maximum number of stops for the scenario
+- It does not exceed the maximum running time for the scenario. (Calculated by <end_time> - <start_time>)
+- It does not have a collision
+
+`A set of logs has the following format:`
+
+```json
+{
+    "simulationRuns": [
+        {
+            "startTime": number (UTC timestamp),
+            "endTime": number (UTC timestamp),
+            "scenarioId": string,
+            "carBuild": string,
+            "result": {
+                "numberOfStops": number,
+                "hasCollision": boolean,
+            }
+        }
+    ],
+    "scenarios": [
+        {
+            "scenarioId": string,
+            "maxNumberOfStops": number,
+            "maxRunningTime": number,
+        }
+    ]
+}
+```
+
+## Interface
+
+The data should be presented as a table of simulation runs with the following format:
+
+| scenarioId | carBuild | startTime | runningTime / maxRunningTime | numberOfStops / maxNumberOfStops | hasCollision | doesScenarioPass |
+
+Each run should be sortable on every column e.g. ascending order of startTime or descending numberOfStops.
+
+The data should be filterable by
+
+- scenarioId
+- carBuild
+- scenarioId and carBuild
+
+Selecting any filter should show the relevant runs and present the following statistics
+
+- percentage of runs that exceed the maximum number of stops
+- percentage of runs that exceed the maximum running time
+- percentage of runs that have a collision
+- percentage of runs that do not pass
+
+## Technical requirements
+
+- Project should be installable and runnable with npm i.e. npm install && npm start
+- Project should be testable with npm test
+- Project must be written using a modern JavaScript framework e.g. Angular, React, etc
+
+- The interface should be clean. Advanced HTML/CSS is not a priority
