10+ Software Development Senior Analyst Interview Questions and Answers

In ASP.NET Core MVC, multiple values can be passed from a controller to a view using ViewData, ViewBag, or a strongly-typed model.

• Use ViewData: Pass values as key-value pairs. Example: ViewData['Message'] = 'Hello World!';

• Use ViewBag: Similar to ViewData but uses dynamic properties. Example: ViewBag.Title = 'My Page';

• Use a ViewModel: Create a class to hold multiple properties. Example: public class MyViewModel { public string Name; public int Age; }

• Return a Tuple: Return mult...read more

Dependency injection enhances code modularity, while Entity Framework simplifies database interactions in ASP.NET MVC applications.

• Dependency Injection (DI): DI is a design pattern that allows for the decoupling of components, making code easier to test and maintain. For example, using a DI container like Autofac or Unity to manage service lifetimes.

• Inversion of Control (IoC): DI is a form of IoC where the control of object creation is transferred to a container, promoting lo...read more

LINQ queries allow for efficient data manipulation and retrieval using left, right, and inner joins in C#.

• Inner Join: Combines records from two collections where there is a match. Example: var result = from a in collectionA join b in collectionB on a.Id equals b.AId select new { a, b };

• Left Join: Returns all records from the left collection and matched records from the right. Example: var result = from a in collectionA join b in collectionB on a.Id equals b.AId into temp from...read more

Flowchart for a given problem statement

• Start with the beginning of the process

• Define decision points and actions

• Use appropriate symbols for processes, decisions, and terminators

• Connect the symbols with arrows to show the flow of the process

• Include loops or repetitions if necessary

Regular expressions in C# are powerful tools for pattern matching and text manipulation using the System.Text.RegularExpressions namespace.

• Use the Regex class: `Regex regex = new Regex(pattern);`

• Match a string: `Match match = regex.Match(input);`

• Find all matches: `MatchCollection matches = regex.Matches(input);`

• Replace text: `string result = regex.Replace(input, replacement);`

• Example pattern: `\d+` matches one or more digits.

Treemap is a sorted map based on natural ordering of keys, while hashmap is an unordered map.

• Treemap stores key-value pairs in sorted order based on the natural ordering of keys.

• Hashmap does not guarantee any specific order of key-value pairs.

• Treemap uses a red-black tree for storage and retrieval, while hashmap uses hash table.

• Treemap is slower than hashmap for most operations due to the sorting overhead.

• Example: TreeMap<String, Integer> treeMap = new TreeMap<>(); HashMap<St...read more

Stream API in Java 8 provides a functional approach to processing collections of objects.

• Stream API allows for processing collections of objects in a functional style.

• It supports operations like filter, map, reduce, and collect.

• Streams can be sequential or parallel, allowing for efficient processing of large datasets.

• Example: List<String> names = Arrays.asList("Alice", "Bob", "Charlie"); names.stream().filter(name -> name.startsWith("A")).forEach(System.out::println);

SDLC stands for Software Development Life Cycle. There are different types including Waterfall, Agile, Iterative, Spiral, V-Model, etc.

• Waterfall: Sequential approach with distinct phases

• Agile: Iterative and incremental development

• Iterative: Repeating cycles of development

• Spiral: Risk-driven approach with multiple iterations

• V-Model: Corresponding testing phase for each development phase

Hibernate sessions manage database interactions and entity states in Java applications using the Hibernate ORM framework.

• A Hibernate session is a single-threaded, short-lived object that represents a conversation between the application and the database.

• It is used to create, read, update, and delete operations on persistent objects (entities).

• Example: session.save(entity) to save an entity to the database.

• Sessions are not thread-safe; each thread should have its own session i...read more

Microservices allow for modular and scalable architecture, while monolithic is simpler but can be harder to maintain.

• Microservices break down applications into smaller, independent services that communicate through APIs.

• Monolithic architecture involves building the entire application as a single unit.

• Microservices offer flexibility, scalability, and fault isolation.

• Monolithic applications are easier to develop and deploy initially.

• Examples of microservices include Netflix, Am...read more
