Round: Test
Experience: The written round was conducted on Hacker Earth and was of 3 hours and had 2 coding questions.1. Comment removal
Given a piece of code, the task was to remove all the comments from the code.Eg. Inputint main(){ // this is a comment int i = 1; /* some more comments */ cout<{"Geeks":"Test1","Are":"hey","Cool":"yeah"}
{"Geeks":"Test1","Are":"20","Cool":['B','C']}
Output:
Are:Cool PS : take special care of input and output format.The questions were easy but the main task was to read the input correctly and string parsing related stuff.Hope this will help you all.

Round: HR Interview
Experience: Two questions of coding. They were easy to program. A link was shared on my email of google docs.
Questions were :-
1. Return an array of fibonacci sequence2. String to number mapping is given find the smallest mapping of number.
for ex. 1=>a, 2=>b , 3=>c ……………
input is 234
find the smallest corresponding to it
brute force solution was required
Round: Technical Interview
Experience: Three questions were asked which were tough to handle
1. HTML parser
2. SQL parser
3. forgot but something on parserHTML parser
A long file was given and we have to find the given html response code and the count of the code in the fileSQL parser
A long file with data about the table formats and the entry in the tables with sql queries to extract the rows count from them that satisfy the criterionPython language will help you to implement the questions easily. (A suggestion)
General Tips: Suggestion- Python language will help you to implement the questions easily.

Round: Test
Experience: There were 2 programs mainly related to app dev which were to be coded in 3 hours.
1. Write a program which takes JSON as input and gives prettified JSON2. C Comment parser.
Round: Test
Experience: There were 3 problems to be solved in 5 hours.
Problem 1:Consider the following series:A := 1B := A*2 + 2C := B*2 + 3 and so on…Write a program that:
outputs the number corresponding to a given letter;given a string of letters like ‘GREP’, computes the sum of the numbers corresponding to all the letters in the string (i.e., G + R + E + P), as given by the above series; andgiven a large number (that would fit into a standard 32-bit integer), finds the shortest string of letters corresponding to it.You may use a greedy approach for the last part. Compute the values of the numbers corresponding to letters as and when required and DO NOT pre-compute beforehand and store them in a data structure
Problem 2:The program will be given a folder named (optional, if not passed assume cwd). The program will print something like this:
$ tree.|-- README.md|-- closure| |-- currencySymbols.js| |-- datetimeSymbolsExt.js| |-- datetimesymbols.js| |-- numberSymbols.js| `-- pluralRules.js|-- e2e| |-- i18n-e2e.js| |-- localeTest_cs.html| |-- localeTest_de.html| |-- localeTest_en.html| |-- localeTest_es.html| |-- localeTest_sk.html| |-- localeTest_zh.html| `-- runner.html|-- generate.sh|-- run-tests.sh|-- spec| |-- closureI18nExtractorSpec.js| |-- converterSpec.js| |-- parserSpec.js| `-- utilSpec.js|-- src| |-- closureI18nExtractor.js| |-- closureSlurper.js| |-- converter.js| |-- parser.js| `-- util.js`-- update-closure.sh
4 directories, 26 filesAn optional second parameter supports filtering the tree with grep like filter, only matching nodes. Eg:
$ tree . src.`-- src |-- closureI18nExtractor.js |-- closureSlurper.js |-- converter.js |-- parser.js `-- util.jsIt should be possible to use arbitrary regex expression for filtering.
Problem 3:In this program you have to consume Twitter.com’s REST API.
Write a program that, given a hashtag H and a number N,
fetches the N most recent images (no duplicates) associated with that hashtagand generates a web-page (an HTML file would do) which displays these images as a simple slideshowYou may attempt this problem in any programming language but you may NOT use a third-party library like twitter4j. You may have to create a new Twitter account if you don’t already have one. Visit Twitter App Management to register a new app and obtain an API key. See Twitter REST API docs for more details.
Problem 3(replacement)*:Write a library in any programming language, that provides a systematic wrapper around the BrowserStack REST API (something similar to twitter4j, which is a Java wrapper around Twitter’s official REST API).
You will be judged on your choice data structures and methods for your library. You can create a test account at -----sign_in. If you then go to your account profile to find your username and authentication key.
Bonus points for packaging the library as a publishable module.
*Due to proxy servers in my college,it was not possible to submit a request to the twitter’s server(at that time who would like to waste time configuring his local machine to handle the issue) so I asked them to give another problem,They were nice and gave me a replacement problem.
Round: Technical Interview
Experience: Most of the questions were related to my projects and internship.He also asked me to rate the knowledge of the programming language I’m most comfortable with and then he asked some very basic but tricky questions from the language.I’d say BrowserStack is one of the company where you don’t work rather you learn exponentially. I’m glad that now I’m a part of it.
General Tips: If possible try to solve the Sudoku problem.

Experience: 1. Write a sql parser to properly parse queries for a particular table. The input will consist of several lines: the first line is of two values, N and M, separated by a comma. The next line has the names of the columns of the table. The next N lines will contain N rows of the table (each column delimited by a comma). After that, the next M lines will contain where clause of sql query which you are supposed to execute and return their output (one in each line).Table input will be in the following format:“ID”,”Name”,”Date” 1,”Narendra Moody”,”2014-10-23 12:21″ . . . 100,”Rahul Pandey”,”2013-11-02 13:01″Query input will be given in following format: ID > 99 and Name = “Rahul Pandely”You are supposed to evaluate query and print the number of rows that come under the criteria.

Explanation
Log file will be given as input over STDIN. You need to write the output over STDOUT.
Input will consist of some lines of web server log given line by line over STDIN. End of input will be given by EOF. In output, print in each line the HTTP code that occurred followed by how many times did they occur (separate two values by space). Output should be sorted in descending order of occurrences.

Experience: 1. Write a sql parser to properly parse queries for a particular table. The input will consist of several lines: the first line is of two values, N and M, separated by a comma. The next line has the names of the columns of the table. The next N lines will contain N rows of the table (each column delimited by a comma). After that, the next M lines will contain where clause of sql query which you are supposed to execute and return their output (one in each line).Table input will be in the following format:“ID”,”Name”,”Date” 1,”Narendra Moody”,”2014-10-23 12:21″ . . . 100,”Rahul Pandey”,”2013-11-02 13:01″Query input will be given in following format: ID > 99 and Name = “Rahul Pandely”You are supposed to evaluate query and print the number of rows that come under the criteria. For example solution for above query will be 1.Sample Input (Plaintext Link)

2. Given HTTP request or response headers, write a program that prints the “request” or “response” based on the input.Also,
In case of a “response”, print the following:
– Response code
– Content-Type of the bodyIn case of a “request”, print the following:
– Value of Accept-Language header, if present
– Resource requestedFor eg:
