Applied through the career site.

First round: Discussion of previous and current professional projects.

Second and third technical rounds: Mostly involved problem-solving questions.

Was not contacted after the third round. Received no reply even when I tried to check with HR after a week, so I assume I failed the technical round.

If enough information for a line is provided, how will you determine if a point is on, above, or below the line?

Find the number of valid substrings in a given string. Example: In "011001010", valid substrings are "01", "1100", "10", "01", "10", "01", "10". Groups of zeros and ones are valid. "1010", though it has the same occurrence of 0s and 1s, is invalid because they are not grouped together.

Determine if string s is divisible by string t. If not, return -1.

Example:

• If string s = "abcdabcdabcdabcd"
• and string t = "abcdabcd" then t can divide s. Return the length of the substring u which divides t, which is 4 (the length of u="abcd").

If s = "abdabdabd" and t = "abdabd", return -1, since t does not divide s.
