2. Interview Rounds:
During these two 45-minute phone interviews, the interviewer first shares a Google Doc with the applicant and poses a medium challenge or two simple problems in algorithms and distributed systems. Before coding the problem on Google Docs during the interview, it is anticipated that the candidate must describe the problem's solution to the interviewer first.
These 45-minute interviews consist of Medium to Hard tasks involving algorithms and DS that the interviewer shares with the candidate in a Google Doc.
The behavioral interview mainly focuses on whether a candidate would fit in with the company's culture.
3. After Interviews:
The recruiter will contact you with feedback following the interview process if your performance is good and the interviews go well and will send your profile to the various Google teams for the team matching phase. During the team matching stage, the team will come to understand your working style and your interests, and you will be able to understand their demands and the team's work expectations.
The recruiter will share the offer letter and announce your hiring once you and the team are ready to begin.
PEP-8 refers to the Python Enhancement Proposal. It is a set of instructions that streamline formatting Python codes. In other words, it is a set of guidelines that help developers how to write Python codes. Also, it provides the best practices for writing robust Python codes.
We can develop Python codes with good consistency and readability following these guidelines. Besides, we can learn how to make naming conventions, code layouts, indentation, comments, whitespaces, etc.
In Python programming, a namespace represents a name assigned to an object. The address and namespace are created instantly whenever an object is created in Python codes.
Python comes with four types of namespaces as follows
Following are the different built-in data types of Python.
|Related Article: Python Tutorial|
A Python Module is nothing but a file that contains executable Python codes. The codes can be variables or functions.
Following are a few built-in Python Modules.
We can combine data frames in Python in the following ways.
Yes. It is crucial to make indents in Python. An indented block in Python consists of codes for loops, functions, classes, etc. We cannot execute the codes properly if we don't indent codes. And it will throw errors.
Below are the reasons why the entire memory is not freed up when a Python program exits.
We can randomize data items in a list using the following codes.
We use ternary operators to determine whether the given condition is true or false. Based on the true or false status of the condition, the direction of program flow execution is decided. The main thing about the ternary operator is that it is more concise than if-else statements. Simply put, a single line of code is enough to use the ternary operator.
Below is the syntax of the Ternary Operator.
Further, we can use ternary operators with lists, tuples, and lambda functions. Ternary operators allow nesting as well.
The following are the salient features of Java.

|Constructors initialize objects and allocate memory||Destructors destroy objects and free up memory|
|Constructors are called Once objects are created.||Destructors are called once Java programs are terminated.|
|They accept arguments. But sometimes, they don’t accept.||They don't take any arguments always.|
|A class may have many constructors.||A class will have a single destructor|
|Constructors can be overloaded||They cannot be overloaded|
|They are executed in successive order||They are usually implemented in reverse order|
|Copy constructors can be used to initialize an object from another object.||Copy constructors are not used.|
Google Cloud Platform or GCP provides high-level security to applications. It is the cloud infrastructure offered by Google. We can create, deploy, and scale applications using this cloud infrastructure. Also, it prevents clients from having their own data centers.
Below are the different components of the Google Cloud platform under various services.

We can read and write files in Java using the following two methods.
The main thing about the callback function is that it runs in the background while the main program is running on the other side.
It is a multiplication function. Multiplication occurs between the numbers defined in the function and the value returned by another function.
It converts one data type into another type automatically. This is done when an expression has two different operand data types.
Boolean coercion, String coercion, and equality coercion are examples of implicit type coercions.
|Spread Operator||REST Parameter|
|It is used in function calls.||It is used in the function declaration.|
It is a collection of unique elements that are neatly ordered. There are three methods in WeakSet such as add (), has (), and delete ().
Moreover, it has only objects. If the objects are not referenced, they will be garbage collected.
A data structure is a format that we use to store, organize, process, and retrieve data systematically. The main thing is that both users as well as machines can understand and manipulate structured data effectively.
Know that the data structure has all the essential data details, such as values, relationships between data, and functions that can be used on the data.
The data structure is crucial in software programming since it is closely connected with algorithms. A data structure is a prime thing for algorithms to perform some basic operations on data.

It is a data structure type that has two nodes. In a way, a binary is the extension of a linked list.
Data structure and data can be changed easily at runtime. The dynamic data structure is the type that allows changes in its size during runtime. It means that a dynamic data structure is contracted or expanded seamlessly while running programs.
The essential thing to note here is that dynamic data structure allows changes in data and structure without affecting other operations connected with the data structure.
Following are a few examples of dynamic data structures.
We can use hashmap as well as doubly linked list data structures to implement the LRU cache.
It has data items that are sequentially ordered. Every data item is stored in a separate memory address.
List and Array are two examples of linear data structures.
We can identify a loop in a linked list with the help of the following three methods.
|It is done at runtime.||Memory allocation is done at compile time.|
|The size of a linked list will change at any time due to the addition and deletion of of new elements.||We must declare the array size.|
This algorithm works based on the divide-and-conquer approach. It uses the pivot to make partitions from a list. The list values smaller than the pivot are grouped at the left partition. The list values greater than the pivot are grouped at the right partition.
It depends on the connectivity of the graph. An undirected graph can have nn-1 number of spanning trees at maximum. Here ‘n’ denotes the number of nodes.
It is a process of cleaning, organizing, and enhancing the raw data into high-quality data organized data. Thus we can make informed decisions from the collected data.
The techniques such as merging, sorting, and joining are used to convert the data into usable data.

|This analytics provides insights into what will happen in the future||The analytics offers insights into what has happened in the past|
|Forecasting and Statistical techniques are used.||Data mining and Data aggregation techniques are used.|
It is an analysis in which we analyze three or more variables. As a result, we understand the relationship of each variable with other variables. For example, analyzing revenue based on expenditure is a multivariate analysis.
We can use many tools to perform multivariate analysis, such as multiple regression, dual-axis charts, cluster analysis, etc.
|It occurs when there are less data to create a model.||It occurs when the model learns random fluctuations|
|Models generate accurate results in the end but poor results at initial times.||Models don’t make accurate predictions.|
|Training errors, as well as testing errors, are significant.||Training error is small, but the testing error is significant.|
|It occurs when the model is simple for the data.||It occurs when the model is complex for the data.|
|To avoid underfitting, we must complicate the model.||To avoid overfitting, we should simplify the model.|
It is a process that includes gathering, processing, transforming, modeling, analyzing, and interpreting data. As a result, we can draw conclusions, make informed decisions, gain valuable insights, and so on.
We can perform data analysis as follows:
The following are the tools widely used for data analysis.
We can view and infer complex data through charts and graphs with data visualization. We can track trends as well as outliers in the data. We can achieve the best from data visualization by removing noise from the input data.
The ideal characteristics of an exemplary data model should be as follows:
KNN is good at approximating the values closer to the missing data. That’s why we prefer using KNN to identify missing numbers in data.
