Caixa Técnico Bancário Novo · Understand the traps and how to avoid them.
Spending the first 60+ minutes on the Conhecimentos Básicos block (Português, Matemática, Atualidades, Informática) and then rushing the Conhecimentos Específicos questions, leaving 15–20 specific questions unanswered or guessed in the final minutes.
The basic block feels familiar and comfortable, so candidates linger on Portuguese interpretation and math word problems, underestimating how much time the specific banking block needs for calculations (interest, amortization, fee percentages).
What to do instead
Before the exam, set a hard time budget per block based on question counts (e.g., if specific questions are 60% of the total, reserve 60% of the time). Practise full-length timed mocks with a visible clock and rehearse the transition point so it becomes automatic.
Reading a Portuguese interpretation text once and answering from memory of the general theme, without locating the exact sentence that supports each alternative.
Under time pressure, candidates trust a global impression of the text; distractor options are built to sound thematically correct while contradicting a specific clause, connective, or pronoun reference.
What to do instead
For every interpretation question, physically point to the line in the text that justifies or refutes each option before marking. Train with exercises that require quoting the supporting sentence in writing, so the habit of locating evidence becomes automatic.
Treating 'mas', 'porém', 'embora', 'portanto', 'porque' and similar connectives as interchangeable, and choosing an answer that keeps the sentence grammatical but reverses the logical relation between clauses.
Candidates check only whether the sentence 'sounds right' rather than identifying the semantic relation (opposition, conclusion, cause, concession) the original text establishes.
What to do instead
Build a personal table of connectives grouped by logical relation (adversidade, conclusão, causa, concessão, finalidade) and drill sentence-rewriting exercises where you must substitute a connective while preserving the exact same relation.
Applying the crase rule by ear and marking 'a' with an accent only when it 'sounds like two a's', failing on cases involving proper names, possessive pronouns, place names, and 'a que/aquele/aquela'.
Spoken Brazilian Portuguese often neutralises the distinction, so auditory intuition fails exactly on the cases examiners favour: before feminine proper nouns, before 'moda', before relative pronouns, and in fixed expressions.
What to do instead
Memorise the structural test: replace the feminine term with a masculine one; if 'ao' appears, crase is required. Drill the exception lists (before masculine words, before verbs, before 'uma', before demonstrative 'esta') with targeted exercises rather than relying on sound.
Solving percentage and financial-math problems by chaining operations in the wrong order (e.g., applying a discount then a markup and assuming they cancel, or adding percentage points to a percentage change), producing a plausible but wrong number.
Candidates carry over everyday intuition that a 10% increase and a 10% decrease offset each other, and they skip writing the algebraic relation, doing steps mentally.
What to do instead
Always write the multiplication chain explicitly using factors (1 + i) and (1 − i), and verify with a concrete base value such as 100. Practise problems combining successive changes, percentage points versus percent, and reverse calculation of the original value.
Confusing simple and compound interest in the middle of a calculation, or using the nominal rate directly when the problem states a different capitalization period, without converting the rate to the period of the transaction.
Formulas look similar and candidates memorise J = C·i·t and M = C·(1+i)^t as isolated recipes, forgetting that 'i' and 't' must share the same time unit and that the stated rate may be nominal.
What to do instead
Start every financial-math question by writing the unit of the rate and the unit of the time side by side, converting before substituting. Practise equivalence of rates (proportional versus equivalent) and problems that explicitly mix monthly rates with annual terms.
Mixing up the Price (francês) and SAC amortization systems, presenting SAC as constant instalments or Price as constant amortization, and then computing the wrong outstanding balance.
Both systems are taught together and the names are not intuitive; candidates memorise 'SAC = decreasing' without anchoring which component is constant in each system.
What to do instead
Anchor on the invariant: in SAC the amortization is constant and instalments decrease; in Price the instalment is constant and amortization grows. Build a full four-period table by hand for both systems and compare the columns until the pattern is unmistakable.
Answering questions about banking products and services from general intuition about 'what a bank does', without distinguishing the specific characteristics, guarantees, and target public of each product (e.g., CDB versus LCI/LCA, poupança versus fundo DI, cheque especial versus crédito pessoal).
Candidates study product names as a list to memorise rather than as a comparison matrix, so they cannot discriminate between options that all describe plausible banking features.
What to do instead
Build a comparison table with rows for each product and columns for issuer, guarantee (FGC or not), liquidity, taxation (IR, IOF), minimum term, and typical user. Review by covering columns and reconstructing them, then answer discrimination questions rather than definition questions.
Confusing the roles and supervision boundaries of the institutions in the National Financial System (Banco Central, CVM, SUSEP, PREVIC, CMN), attributing securities-market supervision to the BCB or insurance supervision to the CVM.
The institutional names are familiar from the news, but candidates never build a clean map of which body regulates, which supervises, and which sets normative policy, so plausible-sounding swaps go unnoticed.
What to do instead
Draw a one-page map linking each institution to its sector (banking/payment, securities, insurance, pension) and to its function (normatização, supervisão, execução de política). Test yourself by classifying institutions and market participants into the correct column.
Ignoring the ethical-conduct and compliance items (sigilo bancário, lavagem de dinheiro, KYC, conflito de interesses, código de conduta) as 'common sense' questions and answering from personal opinion rather than from the stated rule.
These questions look easy and self-evident, so candidates skip the underlying normative content; distractors are then built from reasonable-sounding but legally incorrect behaviour, such as disclosing account data to a family member.
What to do instead
Study the specific rules as rules: the exceptions to bank secrecy, the stages of money laundering, the reporting duty and the role of COAF, and the conduct standards in the professional code. Answer by identifying which norm applies, not which behaviour feels helpful.
