Worley Lead Engineer Interview Questions and Answers

BIM application in highway models involves creating a digital representation of the road and its infrastructure.

• BIM can be used to design and visualize highway projects

• It allows for collaboration between different stakeholders

• BIM can help with clash detection and reduce errors in construction

• It can also be used for maintenance and asset management

• Examples include the use of BIM in the construction of the M25 motorway i

I review/check work of an originator in Civil3D Models by following a systematic approach.

• I check for errors and inconsistencies in the model.

• I verify that the model adheres to the project standards and specifications.

• I ensure that the model is accurate and complete.

• I communicate with the originator to clarify any issues or concerns.

• I document any changes or revisions made to the model.

• I perform a final review before s

Roundabout parameters and values vary based on urban and rural settings.

• Urban roundabouts typically have smaller diameters and tighter curves than rural roundabouts.

• Rural roundabouts may have larger diameters and wider curves to accommodate larger vehicles.

• Speed limits, traffic volume, and pedestrian and cyclist activity also influence roundabout design.

• Roundabout parameters may include lane widths, splitter island wid...read more

ARCADY and PICADY software require input such as road geometry, traffic flow, and vehicle characteristics.

• Road geometry data such as lane widths, radii, and gradients

• Traffic flow data such as traffic volume, speed, and composition

• Vehicle characteristics such as dimensions, speed, and acceleration

• Other inputs such as signal timings and pedestrian crossings

Android architecture stack is a set of layers that make up the Android operating system.

• The stack includes four main layers: Linux kernel, native libraries, Android runtime, and application framework.

• The Linux kernel provides low-level system functionality.

• Native libraries are written in C or C++ and provide access to hardware-specific features.

• The Android runtime includes the Dalvik virtual machine and core libraries.

• ...read more

AIDL stands for Android Interface Definition Language, used for inter-process communication in Android.

• AIDL is used to define the interface between client and service in Android.

• It allows communication between different processes in Android.

• AIDL is used to pass complex data types between processes.

• AIDL is similar to Remote Procedure Call (RPC) in other programming languages.

• Example: AIDL is used in Android to implement...read more

Hash set and hash map are data structures used to store key-value pairs for efficient retrieval.

• Hash set stores unique values without any specific order.

• Hash map stores key-value pairs and allows fast retrieval of values based on keys.

• Both use hashing to map keys to their corresponding values.

• In Java, HashSet and HashMap are implementations of these data structures.
