Placement Papers - MindTree

There were 2 rounds.
1) Aptitude test (by Amcat).
2) Programming test (also by Amcat).

Aptitude test had 3 sessions:

1) Quantitative: Aptitude round is pretty simple. Basics of probability, permutation and combination, time and work, time speed and distance, numbers, percentage, trains (pretty much everything from RS Aggarwal). And surprisingly I got a lot of questions from logarithms (around 4-5). Just basic formulas and tricks are enough to crack it.

2) Logical reasoning: Very easy. Lot of series and blood relation questions.

3) English: Synonyms, antonyms, grammar checking.

Programming test had 2 coding questions. (60 minutes)
