Aequs Programmer Interview Questions, Process, and Tips

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.

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.

There are several types of welding including MIG, TIG, Stick, and Flux-Cored welding.

• MIG welding uses a wire electrode and a shielding gas to join two pieces of metal together.

• TIG welding uses a tungsten electrode and a filler metal to create a strong weld.

• Stick welding uses a consumable electrode coated in flux to create a strong bond.

• Flux-Cored welding uses a wire electrode with a flux core to create a protective shi

1st angle projection is used in Europe & 3rd angle projection is used in North America. They differ in placement of views.

• 1st angle projection places the object in front of the viewing plane while 3rd angle projection places the object behind the viewing plane.

• In 1st angle projection, the top view is placed below the front view while in 3rd angle projection, the top view is placed above the front view.

• 1st angle project...read more

Six Sigma is a data-driven methodology used to improve business processes by reducing defects and variability.

• Six Sigma aims to achieve a level of quality where the probability of defects is extremely low.

• It involves a structured approach to problem-solving using statistical analysis.

• The methodology uses a set of tools and techniques such as DMAIC (Define, Measure, Analyze, Improve, Control) and statistical process con...read more
